Step-by-step explanation:

Step 1: Define

-10(x + 9) + 14x = -42

Step 2: Solve for x

  1. Distribute -10:                              -10x - 90 + 14x = -42
  2. Combine like terms:                   4x - 90 = -42
  3. Add 90 to both sides:                4x = 48
  4. Divide 4 on both sides:              x = 12
