Step-by-step explanation:

Step 1: Define

Identify

50 + x + 10 + 8x + 2x = 650

Step 2: Solve for x

[Addition] Combine like terms:                                                                        11x + 60 = 650[Subtraction Property of Equality] Subtract 60 on both sides:                      11x = 590[Division Property of Equality] Divide both sides by 11:                                  x = 590/11
