    two options. 1. solve the equation for c. 2. plug in each value of the set for c. The one that gives you 25 for the left side is the answer.

    ok. The first number is 4, so start by replacing c with 4 in the equation. 2c + 9 = 25 2*4 + 9 = 25 8 +9 = 25 17 = 25 → this is false, so 4 isn't the answer.
