Each step of a simplification process must be justifiable using the properties of algebra.

  1. Examine the justification for each step in the simplification below.
    Given expression:
    Step 1: Distributive Property
    Step 2: Multiplicative Identity (1 · a = a)
    Step 3: Distributive Property
    Step 4: Definition of Division ()
    Step 5: Associative Property of Addition

  2. Use the properties of algebra to justify each step in simplifying the expression in part (d) of problem

    The steps will be similar to those in the example. Make sure to give appropriate reasons.
