Explanation:

Step 1: Define

14.3 > 5(z - 2) - 2.1

Step 2: Solve for z

  1. Distribute 5: 14.3 > 5z - 10 - 2.1
  2. Subtract: 14.3 > 5z - 12.1
  3. Add 12.1 on both sides: 26.4 > 5z
  4. Divide 5 on both sides: 5.28 > z
  5. Rewrite: z < 5.28

Here we see that any value z smaller than 5.28 would work as a solution to the inequality.
