Step-by-step explanation:

Step 1: Define

Identify

q = -7

r = 2

s = q

8 - 8r - 3s + 6q

Step 2: Simplify

1. Substitute in variables:                                                                                     8 - 8(2) - 3q + 6q
2. Multiply:                                                                                                             8 - 16 - 3q + 6q
3. Combine like terms:                                                                                         3q - 8
