Step-by-step explanation:

Step 1: Define

R(x) = 6x - 3

S(x) = -3x - 8

Step 2: Find

1. Substitute in functions:                                                                                     R(x) - S(x) = 6x - 3 - (-3x - 8)
2. [Distributive Property] Distribute negative:                                                    R(x) - S(x) = 6x - 3 + 3x + 8
3. [Addition] Combine like terms:                                                                        R(x) - S(x) = 9x + 5
