Answer 1

8(а-1)-7а=9
8а-8-7а=9

а=17

Answer 2

To solve the equation 8(a - 1) - 7a = 9 for the value of a, we can follow these steps:

1. Distribute the 8 to the terms inside the parentheses: 8a - 8 - 7a = 9.
2. Combine like terms: (8a - 7a) - 8 = 9. This simplifies to: a - 8 = 9.
3. Add 8 to both sides of the equation to isolate the variable: a - 8 + 8 = 9 + 8. This simplifies to: a = 17.

Therefore, the value of a that satisfies the equation is a = 17.
