a = -2

On the left hand side, multiply each term inside the brackets by 4

Subtract 2 from both sides

Subtract 4a from both sides

Divide both sides by 3

To solve 4(a - 1) = 7a + 2:

- Distribute the 4 across the parentheses: 4a - 4 = 7a + 2
- Rearrange the equation: 4a - 7a = 2 + 4
- Combine like terms: -3a = 6
- Divide both sides by -3: a = -2
