Identify

y + 3 = -y + 9

Step 2: Solve for y

  1. [Addition Property of Equality] Add y on both sides:                                     2y + 3 = 9
  2. [Subtraction Property of Equality] Subtract 3 on both sides:                        2y = 6
  3. [Division Property of Equality] Divide 2 on both sides:                                  y = 3
