Answer 3

To simplify the given expression, let's perform the operations step-by-step:

1. Distribute the negative sign through the parentheses: -(7x - 8) = -7x + 8

2. Combine like terms: 5x - 7 - (7x - 8) = 5x - 7 - 7x + 8

3. Combine the x terms: 5x - 7 - 7x + 8 = (5x - 7x) + (8 - 7)

4. Simplify further: (5x - 7x) + (8 - 7) = -2x + 1

The simplified expression is: -2x + 1
