Step-by-step explanation:

Step 1: Define

1/2(12x + 18) > 99

Step 2: Solve for x

  1. [Multiplication Property of Equality] Multiply 2 on both sides:                    12x + 18 > 198
  2. [Subtraction Property of Equality] Subtract 18 on both sides:                     12x > 180
  3. [Division Property of Equality] Divide 12 on both sides:                              x > 15

Here we see that any value x greater than 15 would work as a solution to the inequality.
