  • Equality Properties

Step-by-step explanation:

Step 1: Define equation

4(x - 1) = 2(6 - 2x)

Step 2: Solve for x

  1. Distribute:                              4x - 4 = 12 - 4x
  2. Add 4x on both sides:          8x - 4 = 12
  3. Add 4 to both sides:             8x = 16
  4. Divide 8 on both sides:        x = 2

Step 3: Check

Plug in x into the original equation to verify it's a solution.

  1. Substitute in x:                    4(2 - 1) = 2(6 - 2(2))
  2. Multiply:                               4(2 - 1) = 2(6 - 4)
  3. Subtract:                              4(1) = 2(2)
  4. Multiply:                               4 = 4

Here we see that 4 does indeed equal 4.

∴ x = 2 is a solution of the equation.
