Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

-4(x + 2) = 4(2 - 2x)

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

  1. Divide -4 on both sides:                    -(x + 2) = 2 - 2x
  2. Distribute negative:                           -x - 2 = 2 - 2x
  3. Add 2x on both sides:                       x - 2 = 2
  4. Add 2 on both sides:                         x = 4

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    -4(4 + 2) = 4(2 - 2(4))
  2. Multiply:                               -4(4 + 2) = 4(2 - 8)
  3. Add/Subtract:                      -4(6) = 4(-6)
  4. Multiply:                               -24 = -24

Here we see that -24 does equal -24.

∴ x = 4 is the solution to the equation.
