Use the Additive Property of Equality to eliminate the subtraction.
c=18
To solve the equation, we have to isolate c on one side. Using the Additive Property of Equality, we will add 7 to both sides of the equation. This will eliminate the subtraction and isolate c.
To check that this solution is correct, substitute c=18 into the original equation and simplify.
Since the left-hand side and right-hand side are equal, c=18 is the correct solution.
