Answer:

x = -8

Step-by-step explanation:

Step 1: Write equation

5x - 7(x + 1) = 9

Step 2: Solve for <em>x</em>

  1. Distribute -7: 5x - 7x - 7 = 9
  2. Combine like terms: -2x - 7 = 9
  3. Add 7 to both sides: -2x = 16
  4. 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
