Step-by-step explanation:

Step 1: Define

-15x + 5 = -10x + 25

Step 2: Solve for x

  1. Add 15x on both sides:                    5 = 5x + 25
  2. Subtract 25 on both sides:              -20 = 5x
  3. Divide 5 on both sides:                   -4 = x
  4. Rewrite:                                             x = -4
