Step-by-step explanation:

<u>Step 1: Define</u>

14x + 18 + x = -112(x + 36) + 13

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

  1. Distribute -112:                         14x + 18 + x = -112x - 4032 + 13
  2. Combine like terms:                15x + 18 = -112x - 4019
  3. Add 112x on both sides;          127x + 18 = -4019
  4. Isolate <em>x</em> term:                          127x = -4037
  5. Isolate <em>x</em>:                                   x = -4037/127
