$$
Subtract 4:
$$
\frac{7x}{9} = -5
$$
Multiply by 9:
$$
7x = -45 \Rightarrow x = -\frac{45}{7}
$$

✔ Answer: $x = -\frac{45}{7}$

---

✔ Section B

#### 1) $4(2x - 3) = 8(2x + 5)$

---

#### 11) $4x - (2x - 8) = 5(1 + 2x)$

Simplify left:
$$
4x - 2x + 8 = 2x + 8
$$
Right: $5 + 10x$
So:
$$
2x + 8 = 5 + 10x \Rightarrow 8 - 5 = 10x - 2x \Rightarrow 3 = 8x \Rightarrow x = \frac{3}{8}
$$

✔ Answer: $x = \frac{3}{8}$

---

#### 12) $10 - 6(8x - 2) = 9x - (3 + 4x)$

Expand:
Left: $10 - 48x + 12 = 22 - 48x$
Right: $9x - 3 - 4x = 5x - 3$

So:
$$
22 - 48x = 5x - 3
$$
Add $48x$:
$$
22 = 53x - 3 \Rightarrow 25 = 53x \Rightarrow x = \frac{25}{53}
$$

✔ Answer: $x = \frac{25}{53}$

---

✔ Section C

#### 1) $\frac{5x - 2}{3} = \frac{4x + 1}{2}$

Cross-multiply:
$$
2(5x - 2) = 3(4x + 1)
\Rightarrow 10x - 4 = 12x + 3
\Rightarrow -4 - 3 = 12x - 10x \Rightarrow -7 = 2x \Rightarrow x = -\frac{7}{2}
$$

✔ Answer: $x = -\frac{7}{2}$

---

#### 2) $\frac{7x - 8}{5} = \frac{2x + 5}{4}$

Cross-multiply:
$$
4(7x - 8) = 5(2x + 5)
\Rightarrow 28x - 32 = 10x + 25
\Rightarrow 18x = 57 \Rightarrow x = \frac{57}{18} = \frac{19}{6}
$$

✔ Answer: $x = \frac{19}{6}$

---

#### 3) $\frac{-8x - 1}{2} = \frac{5 - 3x}{6}$

Multiply both sides by 6:
$$
3(-8x - 1) = 5 - 3x \Rightarrow -24x - 3 = 5 - 3x
\Rightarrow -24x + 3x = 5 + 3 \Rightarrow -21x = 8 \Rightarrow x = -\frac{8}{21}
$$

✔ Answer: $x = -\frac{8}{21}$

---

#### 4) $\frac{5(x + 11)}{3} = \frac{3(1 + x)}{2}$

Cross-multiply:
$$
2 \cdot 5(x + 11) = 3 \cdot 3(1 + x)
\Rightarrow 10(x + 11) = 9(1 + x)
\Rightarrow 10x + 110 = 9 + 9x
\Rightarrow 10x - 9x = 9 - 110 \Rightarrow x = -101
$$

✔ Answer: $x = -101$

---

#### 5) $\frac{3(2 + 5x)}{4} = \frac{2(6x - 3)}{5}$

Cross-multiply:
$$
5 \cdot 3(2 + 5x) = 4 \cdot 2(6x - 3)
\Rightarrow 15(2 + 5x) = 8(6x - 3)
\Rightarrow 30 + 75x = 48x - 24
\Rightarrow 75x - 48x = -24 - 30 \Rightarrow 27x = -54 \Rightarrow x = -2
$$

✔ Answer: $x = -2$

---

#### 6) $\frac{2(3x - 5)}{3} = \frac{-4(x - 2)}{7}$

Cross-multiply:
$$
7 \cdot 2(3x - 5) = 3 \cdot (-4)(x - 2)
\Rightarrow 14(3x - 5) = -12(x - 2)
\Rightarrow 42x - 70 = -12x + 24
\Rightarrow 42x + 12x = 24 + 70 \Rightarrow 54x = 94 \Rightarrow x = \frac{94}{54} = \frac{47}{27}
$$

✔ Answer: $x = \frac{47}{27}$

---

#### 7) $\frac{1}{2}(2x - 6) = \frac{1}{4}(8 - 12x)$

Simplify both sides:
Left: $x - 3$
Right: $2 - 3x$

So:
$$
x - 3 = 2 - 3x \Rightarrow x + 3x = 2 + 3 \Rightarrow 4x = 5 \Rightarrow x = \frac{5}{4}
$$

✔ Answer: $x = \frac{5}{4}$

---

#### 8) $\frac{1}{2}(5x + 7) = \frac{3}{4}(3x - 1)$

Multiply both sides by 4 to eliminate denominators:
$$
4 \cdot \frac{1}{2}(5x + 7) = 4 \cdot \frac{3}{4}(3x - 1)
\Rightarrow 2(5x + 7) = 3(3x - 1)
\Rightarrow 10x + 14 = 9x - 3
\Rightarrow 10x - 9x = -3 - 14 \Rightarrow x = -17
$$

✔ Answer: $x = -17$

---

#### 9) $\frac{5}{3x + 1} = 12$

Multiply both sides by $3x + 1$:
$$
5 = 12(3x + 1) \Rightarrow 5 = 36x + 12 \Rightarrow -7 = 36x \Rightarrow x = -\frac{7}{36}
$$

✔ Answer: $x = -\frac{7}{36}$

---

#### 10) $\frac{x + 2}{x + 3} = 4$

Multiply both sides by $x + 3$:
$$
x + 2 = 4(x + 3) = 4x + 12
\Rightarrow x - 4x = 12 - 2 \Rightarrow -3x = 10 \Rightarrow x = -\frac{10}{3}
$$

✔ Answer: $x = -\frac{10}{3}$

---

#### 11) $\frac{2x - 9}{3x - 2} = -3$

Multiply both sides by $3x - 2$:
$$
2x - 9 = -3(3x - 2) = -9x + 6
\Rightarrow 2x + 9x = 6 + 9 \Rightarrow 11x = 15 \Rightarrow x = \frac{15}{11}
$$

✔ Answer: $x = \frac{15}{11}$

---

#### 12) $\frac{2}{3x + 10} = \frac{1}{x - 1}$

Cross-multiply:
$$
2(x - 1) = 1(3x + 10) \Rightarrow 2x - 2 = 3x + 10
\Rightarrow -2 - 10 = 3x - 2x \Rightarrow -12 = x
$$

✔ Answer: $x = -12$

---

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

Cross-multiply:
$$
2(2x - 5) = 9(7x + 3) \Rightarrow 4x - 10 = 63x + 27
\Rightarrow -10 - 27 = 63x - 4x \Rightarrow -37 = 59x \Rightarrow x = -\frac{37}{59}
$$

✔ Answer: $x = -\frac{37}{59}$

---

#### 14) $\frac{8}{6x + 12} = -\frac{11}{7x - 10}$

Note: $6x + 12 = 6(x + 2)$

Cross-multiply:
$$
8(7x - 10) = -11(6x + 12)
\Rightarrow 56x - 80 = -66x - 132
\Rightarrow 56x + 66x = -132 + 80 \Rightarrow 122x = -52 \Rightarrow x = -\frac{52}{122} = -\frac{26}{61}
$$

✔ Answer: $x = -\frac{26}{61}$
