Equality Properties

Step-by-step explanation:

<u>Step 1: Define</u>

-2(x - 3) < 4

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

  1. Divide -2 on both sides:                    x - 3 > -2
  2. Add 3 to both sides:                          x > 1

Here we see that any value <em>x</em> greater than 1 would work as a solution to the equation.
