Answer 3

Solving the Equation 1 + 8(-x + 10) = 9

To solve the equation 1 + 8(-x + 10) = 9, we can follow these steps:

1. Distribute the 8 to the terms inside the parentheses: 1 + 8(-x + 10) = 9 1 - 8x + 80 = 9

2. Combine like terms: -8x + 81 = 9

3. Subtract 81 from both sides of the equation: -8x = 9 - 81 -8x = -72

4. Divide both sides of the equation by -8 to solve for x: x = -72 / -8 x = 9

Therefore, the solution to the equation 1 + 8(-x + 10) = 9 is x = 9.
