• Division Property of Equality
• Addition Property of Equality
• Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

9 - 5x < 54

Step 2: Solve for x

1. [Subtraction Property of Equality] Subtract 9 on both sides:                      -5x < 45
2. [Division Property of Equality] Divide -5 on both sides:                              x > -9

Here we see that any value x greater than -9 would work as a solution to the inequality.
