*Equations with Variables on Both Sides*

#### Intro

To solve an equation that has variables on both sides, use the Addition or Subtraction Properties of Equality to get the variable on one side of the equation.

#### Sample Problem

Solve 6x + 3 = 8x – 21.

#### Solution

6x + 3 = 8x – 21

6x + 3 -6x= 8x – 21 -6x ~Subtract 6x from both sides.

3 = 2x – 21 ~Combine like terms.

3 + 21 = 2x – 21 + 21 ~Add 21 to both sides.

24 = 2x ~Simplify.

24 / 2 = 2x / 2 ~Divide each side by 2.

x = 12 ~Simplify.
