Equality Properties

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

Step-by-step explanation:

<u>Step 1: Define</u>

4x - 8 > 32

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Add 8 on both sides:                    4x > 40
  2. Divide 4 on both sides:                x > 10

Here we see that any value <em>x</em> greater than 10 would work as a solution to the inequality.
