Step-by-step explanation:

Step 1: Define

-2(5x - 5.5) + 8 = -9x + 2 - (-5)

Step 2: Solve for x

  1. Distribute:                              -10x + 11 + 8 = -9x + 2 + 5
  2. Combine like terms:              -10x + 19 = -9x + 7
  3. Add 10x to both sides:          19 = x + 7
  4. Subtract 7 on both sides:     12 = x
  5. Rewrite:                                  x = 12
