• Addition Property of Equality
• Subtraction Property of Equality

Step-by-step explanation:

Step 1: Define

$\displaystyle -\frac{3}{4}x + 2 \leq -7$

Step 2: Solve for x

1. [Subtraction Property of Equality] Isolate x term:                                           $\displaystyle -\frac{3}{4}x \leq -9$
2. [Division Property of Equality] Isolate x:                                                         $\displaystyle x \leq 12$

Here we see that any value x smaller than or equal to 12 would work as a solution to the inequality.
