Step-by-step explanation:

Step 1: Define

-3.5(x + 12) = -2x + 18

Step 2: Solve for x

  1. Distribute -3.5:                              -3.5x - 42 = -2x + 18
  2. Add 3.5x on both sides:               -42 = 1.5x + 18
  3. Subtract 18 on both sides:           -60 = 1.5x
  4. Divide 1.5 on both sides:              -40 = x
  5. Rewrite:                                         x = -40
