Step-by-step explanation:

Step 1: Define

15.6 < 2.7(z - 1) - 0.6

Step 2: Solve for z

  1. [Addition Property of Equality] Add 0.6 on both sides:                                 16.2 < 2.7(z - 1)
  2. [Division Property of Equality] Divide 2.7 on both sides:                               6 < z - 1
  3. [Addition Property of Equality] Add 1 on both sides:                                     7 < z
  4. Rewrite:                                                                                                             z > 7

Here we see that any value z greater than 7 would work as a solution to the inequality.
