Step-by-step explanation:

Step 1: Define

Identify.

x - y = 5

Step 2: Solve

1. Factor:                                                                                                               $\displaystyle 6x - 6y = 6(x - y)$
2. Substitute in expression:                                                                                 $\displaystyle 6x - 6y = 6(5)$
3. [Order of Operations] Evaluate:                                                                      $\displaystyle 6x - 6y = 30$
