To solve the given linear equations, we will go through each section step by step. Here are the solutions:

---

Section A



#### 1) $\frac{2x + 5}{3} = 11$
Multiply both sides by 3:
$$
2x + 5 = 33
$$
Subtract 5 from both sides:
$$
2x = 28
$$
Divide by 2:
$$
x = 14
$$

#### 2) $\frac{8 - 3x}{2} = 5$
Multiply both sides by 2:
$$
8 - 3x = 10
$$
Subtract 8 from both sides:
$$
-3x = 2
$$
Divide by -3:
$$
x = -\frac{2}{3}
$$

#### 3) $\frac{5 - 9x}{6} = -2$
Multiply both sides by 6:
$$
5 - 9x = -12
$$
Subtract 5 from both sides:
$$
-9x = -17
$$
Divide by -9:
$$
x = \frac{17}{9}
$$

#### 4) $\frac{7x + 6}{3} - 9 = -12$
Add 9 to both sides:
$$
\frac{7x + 6}{3} = -3
$$
Multiply both sides by 3:
$$
7x + 6 = -9
$$
Subtract 6 from both sides:
$$
7x = -15
$$
Divide by 7:
$$
x = -\frac{15}{7}
$$

#### 5) $8x + \frac{1 - 4x}{8} = 7$
Multiply every term by 8 to clear the fraction:
$$
64x + (1 - 4x) = 56
$$
Simplify:
$$
64x + 1 - 4x = 56
$$
$$
60x + 1 = 56
$$
Subtract 1 from both sides:
$$
60x = 55
$$
Divide by 60:
$$
x = \frac{55}{60} = \frac{11}{12}
$$

#### 6) $\frac{5}{x} = -6$
Multiply both sides by $x$:
$$
5 = -6x
$$
Divide by -6:
$$
x = -\frac{5}{6}
$$

#### 7) $\frac{11}{4x} + 9 = 3$
Subtract 9 from both sides:
$$
\frac{11}{4x} = -6
$$
Multiply both sides by $4x$:
$$
11 = -24x
$$
Divide by -24:
$$
x = -\frac{11}{24}
$$

#### 8) $5 - \frac{3x}{4} = 8x$
Multiply every term by 4 to clear the fraction:
$$
20 - 3x = 32x
$$
Add $3x$ to both sides:
$$
20 = 35x
$$
Divide by 35:
$$
x = \frac{20}{35} = \frac{4}{7}
$$

#### 9) $2 + \frac{4x}{3} - 7 = 1$
Simplify the left side:
$$
\frac{4x}{3} - 5 = 1
$$
Add 5 to both sides:
$$
\frac{4x}{3} = 6
$$
Multiply both sides by 3:
$$
4x = 18
$$
Divide by 4:
$$
x = \frac{18}{4} = \frac{9}{2}
$$

#### 10) $4 - \frac{3x}{2} = 3x + 5$
Subtract 4 from both sides:
$$
-\frac{3x}{2} = 3x + 1
$$
Multiply every term by 2 to clear the fraction:
$$
-3x = 6x + 2
$$
Subtract $6x$ from both sides:
$$
-9x = 2
$$
Divide by -9:
$$
x = -\frac{2}{9}
$$

#### 11) $6 - \frac{2}{x} = 10$
Subtract 6 from both sides:
$$
-\frac{2}{x} = 4
$$
Multiply both sides by $x$:
$$
-2 = 4x
$$
Divide by 4:
$$
x = -\frac{1}{2}
$$

#### 12) $4 - \frac{2x}{9} + x = -1$
Combine like terms:
$$
4 + \left(x - \frac{2x}{9}\right) = -1
$$
Write $x$ as $\frac{9x}{9}$:
$$
4 + \frac{9x - 2x}{9} = -1
$$
$$
4 + \frac{7x}{9} = -1
$$
Subtract 4 from both sides:
$$
\frac{7x}{9} = -5
$$
Multiply both sides by 9:
$$
7x = -45
$$
Divide by 7:
$$
x = -\frac{45}{7}
$$

Section B



#### 1) $4(2x - 3) = 8(2x + 5)$
Expand both sides:
$$
8x - 12 = 16x + 40
$$
Subtract $8x$ from both sides:
$$
-12 = 8x + 40
$$
Subtract 40 from both sides:
$$
-52 = 8x
$$
Divide by 8:
$$
x = -\frac{52}{8} = -\frac{13}{2}
$$

#### 2) $3(4x - 5) = 5(2x - 5)$
Expand both sides:
$$
12x - 15 = 10x - 25
$$
Subtract $10x$ from both sides:
$$
2x - 15 = -25
$$
Add 15 to both sides:
$$
2x = -10
$$
Divide by 2:
$$
x = -5
$$

#### 3) $8(6x + 2) = 5(x - 2)$

$$
43x + 16 = -10
$$
Subtract 16 from both sides:
$$
43x = -26
$$
Divide by 43:
$$
x = -\frac{26}{43}
$$

#### 4) $2(3x - 4) = 7(11 - 2x)$
Expand both sides:
$$
6x - 8 = 77 - 14x
$$
Add $14x$ to both sides:
$$
20x - 8 = 77
$$
Add 8 to both sides:
$$
20x = 85
$$
Divide by 20:
$$
x = \frac{85}{20} = \frac{17}{4}
$$

#### 5) $7(5 - x) = -4(x - 11)$
Expand both sides:
$$
35 - 7x = -4x + 44
$$
Add $4x$ to both sides:
$$
35 - 3x = 44
$$
Subtract 35 from both sides:
$$
-3x = 9
$$
Divide by -3:
$$
x = -3
$$

#### 6) $-4(x - 8) = -6(4 + 3x)$
Expand both sides:
$$
-4x + 32 = -24 - 18x
$$
Add $18x$ to both sides:
$$
14x + 32 = -24
$$
Subtract 32 from both sides:
$$
14x = -56
$$
Divide by 14:
$$
x = -4
$$

#### 7) $7(4 - 3x) = 2(8x - 9) + 6$
Expand both sides:
$$
28 - 21x = 16x - 18 + 6
$$
Simplify the right side:
$$
28 - 21x = 16x - 12
$$
Add $21x$ to both sides:
$$
28 = 37x - 12
$$
Add 12 to both sides:
$$
40 = 37x
$$
Divide by 37:
$$
x = \frac{40}{37}
$$

#### 8) $-6(3 - 4x) + 2x = 8(x + 11)$
Expand both sides:
$$
-18 + 24x + 2x = 8x + 88
$$
Simplify:
$$
-18 + 26x = 8x + 88
$$
Subtract $8x$ from both sides:
$$
-18 + 18x = 88
$$
Add 18 to both sides:
$$
18x = 106
$$
Divide by 18:
$$
x = \frac{106}{18} = \frac{53}{9}
$$

#### 9) $3(2x - 6) = 3 - 4(3 - x)$
Expand both sides:
$$
6x - 18 = 3 - 12 + 4x
$$
Simplify the right side:
$$
6x - 18 = -9 + 4x
$$
Subtract $4x$ from both sides:
$$
2x - 18 = -9
$$
Add 18 to both sides:
$$
2x = 9
$$
Divide by 2:
$$
x = \frac{9}{2}
$$

#### 10) $9(2x - 1) - 3x = 3(12 + x)$
Expand both sides:
$$
18x - 9 - 3x = 36 + 3x
$$
Simplify:
$$
15x - 9 = 36 + 3x
$$
Subtract $3x$ from both sides:
$$
12x - 9 = 36
$$
Add 9 to both sides:
$$
12x = 45
$$
Divide by 12:
$$
x = \frac{45}{12} = \frac{15}{4}
$$

#### 11) $4x - (2x - 8) = 5(1 + 2x)$
Expand both sides:
$$
4x - 2x + 8 = 5 + 10x
$$
Simplify:
$$
2x + 8 = 5 + 10x
$$
Subtract $2x$ from both sides:
$$
8 = 5 + 8x
$$
Subtract 5 from both sides:
$$
3 = 8x
$$
Divide by 8:
$$
x = \frac{3}{8}
$$

#### 12) $10 - 6(8x - 2) = 9x - (3 + 4x)$
Expand both sides:
$$
10 - 48x + 12 = 9x - 3 - 4x
$$
Simplify:
$$
22 - 48x = 5x - 3
$$
Add $48x$ to both sides:
$$
22 = 53x - 3
$$
Add 3 to both sides:
$$
25 = 53x
$$
Divide by 53:
$$
x = \frac{25}{53}
$$

$$
x = \frac{57}{18} = \frac{19}{6}
$$

#### 3) $\frac{-8x - 1}{2} = \frac{5 - 3x}{6}$
Cross-multiply:
$$
6(-8x - 1) = 2(5 - 3x)
$$
Expand both sides:
$$
-48x - 6 = 10 - 6x
$$
Add $48x$ to both sides:
$$
-6 = 42x + 10

2 \cdot 5(x + 11) = 3 \cdot 3(1 + x)
$$
Expand both sides:
$$
10(x + 11) = 9(1 + x)
$$
$$
10x + 110 = 9 + 9x
$$
Subtract $9x$ from both sides:
$$
x + 110 = 9
$$
Subtract 110 from both sides:
$$
x = -101
$$

#### 5) $\frac{3(2 + 5x)}{4} = \frac{2(6x - 3)}{5}$
Cross-multiply:
$$
5 \cdot 3(2 + 5x) = 4 \cdot 2(6x - 3)
$$
Expand both sides:
$$
15(2 + 5x) = 8(6x - 3)
$$
$$
30 + 75x = 48x - 24
$$
Subtract $48x$ from both sides:
$$
30 + 27x = -24
$$
Subtract 30 from both sides:
$$
27x = -54
$$
Divide by 27:
$$
x = -2
$$

#### 6) $\frac{2(3x - 5)}{3} = \frac{-4(x - 2)}{7}$
Cross-multiply:
$$
7 \cdot 2(3x - 5) = 3 \cdot (-4)(x - 2)
$$
Expand both sides:
$$
14(3x - 5) = -12(x - 2)
$$
$$
42x - 70 = -12x + 24
$$
Add $12x$ to both sides:
$$
54x - 70 = 24
$$
Add 70 to both sides:
$$
54x = 94
$$
Divide by 54:
$$
x = \frac{94}{54} = \frac{47}{27}
$$

#### 7) $\frac{1}{2}(2x - 6) = \frac{1}{4}(8 - 12x)$
Simplify both sides:
$$
x - 3 = 2 - 3x
$$
Add $3x$ to both sides:
$$
4x - 3 = 2
$$
Add 3 to both sides:
$$
4x = 5
$$
Divide by 4:
$$
x = \frac{5}{4}
$$

#### 8) $\frac{1}{2}(5x + 7) = \frac{3}{4}(3x - 1)$
Cross-multiply:
$$
2 \cdot \frac{1}{2}(5x + 7) = 4 \cdot \frac{3}{4}(3x - 1)
$$
Simplify:
$$
5x + 7 = 3(3x - 1)
$$
Expand:
$$
5x + 7 = 9x - 3
$$
Subtract $5x$ from both sides:
$$
7 = 4x - 3
$$
Add 3 to both sides:
$$
10 = 4x
$$
Divide by 4:
$$
x = \frac{10}{4} = \frac{5}{2}
$$

#### 9) $\frac{5}{3x + 1} = 12$
Multiply both sides by $3x + 1$:
$$
5 = 12(3x + 1)
$$
Expand:
$$
5 = 36x + 12
$$
Subtract 12 from both sides:
$$
-7 = 36x
$$
Divide by 36:
$$
x = -\frac{7}{36}
$$

#### 10) $\frac{x + 2}{x + 3} = 4$
Multiply both sides by $x + 3$:
$$
x + 2 = 4(x + 3)
$$
Expand:
$$
x + 2 = 4x + 12
$$
Subtract $x$ from both sides:
$$
2 = 3x + 12
$$

$$
11x = 15
$$
Divide by 11:
$$
x = \frac{15}{11}
$$

#### 12) $\frac{2}{3x + 10} = \frac{1}{x - 1}$
Cross-multiply:
$$
2(x - 1) = 1(3x + 10)
$$
Expand:

2x - 2 = 3x + 10
$$
Subtract $2x$ from both sides:
$$
-2 = x + 10
$$
Subtract 10 from both sides:
$$
x = -12
$$

#### 13) $\frac{2}{7x + 3} = \frac{9}{2x - 5}$
Cross-multiply:
$$
2(2x - 5) = 9(7x + 3)

$$
Subtract $4x$ from both sides:
$$
-10 = 59x + 27
$$
Subtract 27 from both sides:
$$
-37 = 59x
$$
Divide by 59:
$$
x = -\frac{37}{59}
$$

#### 14) $\frac{8}{6x + 12} = -\frac{11}{7x - 10}$
Cross-multiply:
$$
8(7x - 10) = -11(6x + 12)
$$
Expand:
$$
56x - 80 = -66x - 132
$$
Add $66x$ to both sides:
$$
122x - 80 = -132
$$
Add 80 to both sides:
$$
122x = -52
$$
Divide by 122:
$$
x = -\frac{52}{122} = -\frac{26}{61}
$$
