Question

X+12/8x-7 - 2x-7/7-8x

Answer 1

19-x/8x-7 ну вроде так)

Answer 2

To simplify the expression (x + 12)/(8x - 7) - (2x - 7)/(7 - 8x), we can follow these steps:

1. Factor out a negative sign from the second fraction: (x + 12)/(8x - 7) + (7 - 2x)/(8x - 7)

2. Since the denominators in both fractions are the same (8x - 7), we can combine the numerators into a single fraction: [(x + 12) + (7 - 2x)]/(8x - 7)

3. Now, let's simplify the numerators: (x + 12 + 7 - 2x)/(8x - 7)

4. Combine like terms in the numerator: (x - 2x + 12 + 7)/(8x - 7)

5. Further simplify the numerator: (-x + 19)/(8x - 7)

So, the simplified expression is (-x + 19)/(8x - 7).
