  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality

<u>Algebra I</u>

  • Terms/Coefficients

  1. [Distributive Property] Distribute 1/2:                                                              4x - 2 = 2x
  2. [Subtraction Property of Equality] Subtract 2x on both sides:                      2x - 2 = 0
  3. [Addition Property of Equality] Add 2 on both sides:                                    2x = 2
  4. [Division Property of Equality] Divide 2 on both sides:                                  x = 1
