Algebraic equations worksheet with problems ranging from simple linear equations to more complex expressions involving fractions and parentheses.

Problem: Solve the given equations step by step.

We will solve each equation systematically. Let's start with the first equation from part (a) and proceed through all the equations.

---

#### (a) \( 2(x-1) - 3(x-2) + 4(x-3) = 2(x+5) \)

1. Expand each term:
\[
2(x-1) = 2x - 2
\]
\[
-3(x-2) = -3x + 6
\]
\[
4(x-3) = 4x - 12
\]
\[
2(x+5) = 2x + 10
\]

2. Substitute these expansions into the equation:
\[
(2x - 2) + (-3x + 6) + (4x - 12) = 2x + 10
\]

3. Combine like terms on the left-hand side:
\[
2x - 3x + 4x - 2 + 6 - 12 = 2x + 10
\]
\[
(2x - 3x + 4x) + (-2 + 6 - 12) = 2x + 10
\]
\[
3x - 8 = 2x + 10
\]

4. Isolate \( x \):
\[
3x - 2x = 10 + 8
\]
\[
x = 18
\]

Solution for (a): \( \boxed{x = 18} \)

---

#### (b) \( 2(3+4x) - 2 = 3 - 5(1-x) \)

1. Expand each term:
\[
2(3+4x) = 6 + 8x
\]
\[
-5(1-x) = -5 + 5x
\]

2. Substitute these expansions into the equation:
\[
(6 + 8x) - 2 = 3 - (5 - 5x)
\]
\[
6 + 8x - 2 = 3 - 5 + 5x
\]

3. Simplify both sides:
\[
4 + 8x = -2 + 5x
\]

4. Isolate \( x \):
\[
8x - 5x = -2 - 4
\]
\[
3x = -6
\]
\[
x = -2
\]

Solution for (b): \( \boxed{x = -2} \)

---

#### (c) \( \frac{a}{3} - \frac{5}{3} - \frac{a-3}{4} = \frac{3}{4} + 1 \)

1. Combine constants on the right-hand side:
\[
\frac{3}{4} + 1 = \frac{3}{4} + \frac{4}{4} = \frac{7}{4}
\]

2. Rewrite the equation:
\[
\frac{a}{3} - \frac{5}{3} - \frac{a-3}{4} = \frac{7}{4}
\]

3. Find a common denominator (12) for all fractions:
\[
\frac{a}{3} = \frac{4a}{12}, \quad \frac{5}{3} = \frac{20}{12}, \quad \frac{a-3}{4} = \frac{3(a-3)}{12} = \frac{3a - 9}{12}, \quad \frac{7}{4} = \frac{21}{12}
\]

4. Substitute these into the equation:
\[
\frac{4a}{12} - \frac{20}{12} - \frac{3a - 9}{12} = \frac{21}{12}
\]

5. Combine the fractions on the left-hand side:
\[
\frac{4a - 20 - (3a - 9)}{12} = \frac{21}{12}
\]
\[
\frac{4a - 20 - 3a + 9}{12} = \frac{21}{12}
\]
\[
\frac{a - 11}{12} = \frac{21}{12}
\]

6. Eliminate the denominators by multiplying through by 12:
\[
a - 11 = 21
\]

7. Solve for \( a \):
\[
a = 32
\]

Solution for (c): \( \boxed{a = 32} \)

---

#### (d) \( \frac{5}{3}(t-2) - \frac{4}{5}(2t-5) = 4 - \frac{3}{2}(t-3) \)

1. Expand each term:
\[
\frac{5}{3}(t-2) = \frac{5t}{3} - \frac{10}{3}
\]
\[
\frac{4}{5}(2t-5) = \frac{8t}{5} - \frac{20}{5} = \frac{8t}{5} - 4
\]
\[
\frac{3}{2}(t-3) = \frac{3t}{2} - \frac{9}{2}
\]

2. Substitute these expansions into the equation:
\[
\left( \frac{5t}{3} - \frac{10}{3} \right) - \left( \frac{8t}{5} - 4 \right) = 4 - \left( \frac{3t}{2} - \frac{9}{2} \right)
\]

3. Simplify both sides:
\[
\frac{5t}{3} - \frac{10}{3} - \frac{8t}{5} + 4 = 4 - \frac{3t}{2} + \frac{9}{2}
\]

4. Combine constants on the right-hand side:
\[
4 + \frac{9}{2} = \frac{8}{2} + \frac{9}{2} = \frac{17}{2}
\]

5. Rewrite the equation:
\[
\frac{5t}{3} - \frac{10}{3} - \frac{8t}{5} + 4 = \frac{17}{2} - \frac{3t}{2}
\]

6. Find a common denominator (30) for all fractions:
\[
\frac{5t}{3} = \frac{50t}{30}, \quad \frac{10}{3} = \frac{100}{30}, \quad \frac{8t}{5} = \frac{48t}{30}, \quad 4 = \frac{120}{30}, \quad \frac{17}{2} = \frac{255}{30}, \quad \frac{3t}{2} = \frac{45t}{30}
\]

7. Substitute these into the equation:
\[
\frac{50t}{30} - \frac{100}{30} - \frac{48t}{30} + \frac{120}{30} = \frac{255}{30} - \frac{45t}{30}
\]

8. Combine the fractions on the left-hand side:
\[
\frac{50t - 48t - 100 + 120}{30} = \frac{255 - 45t}{30}
\]
\[
\frac{2t + 20}{30} = \frac{255 - 45t}{30}
\]

9. Eliminate the denominators by multiplying through by 30:
\[
2t + 20 = 255 - 45t
\]

10. Isolate \( t \):
\[
2t + 45t = 255 - 20
\]
\[
47t = 235
\]
\[
t = 5
\]

Solution for (d): \( \boxed{t = 5} \)
