Module 2- Two-step Equations and I
1. Use the distributive property to solve for x
7(4x + 9) – 10 = -87

Answer 1

`-5 = x`

Explanation:

`7(4x + 9) - 10 = -87 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: + \: 10 \: \: \: \: + 10 \\ \\ (7(4x + 9))/(7) = -(77)/(7) \\ \\ 4x + 9 = -11 \\ \: \: \: \: \: \: -\: 9 \: \: \: \: \: - \: 9 \\ \\ (4x)/(4) = -(20)/(4) \\ \\ x = -5`

** The above answer is written in reverse, which is the exact same result.
