Answer:
x = -8
Step-by-step explanation:
Step 1: Write equation
5x - 7(x + 1) = 9
Step 2: Solve for <em>x</em>
- Distribute -7: 5x - 7x - 7 = 9
- Combine like terms: -2x - 7 = 9
- Add 7 to both sides: -2x = 16
- Divide both sides by -2: x = -8
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
5(-8) - 7(-8 + 1) = 9
-40 - 7(-7) = 9
-40 + 49 = 9
9 = 9
