6-92.

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

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 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.
