Step-by-step explanation:

Step 1: Define

9(2x + 1) < 9x - 18

Step 2: Solve for x

  1. Distribute 9:                    18x + 9 < 9x - 18
  2. Isolate x terms:               9x + 9 < -18
  3. Isolate x term:                 9x < -27
  4. Isolate x:                          x < -3

Here we see any value x smaller than -3 would work as a solution to the inequality.
