4. Solving Equations with Variables on Both Sides Objective: To learn to solve equations with variables on both sides of the equation.  To solve an equation that has variables on both sides: After you simplify each side of the equation, you must use the Addition or Subtraction Properties of Equality to move the all variables to one side of the equation.

5. Example 1 Solve and Check. 3m + 2 = -6 – m

6. Example 2 Solve and Check. 2(n – 6) = 9n + 2

7. Example 3 Solve and Check. 4g + 7 – 2g = 5g – 2

8. Example 4 Solve and Check. 4(n – 2) = 6n + 5 – 2n

9. Example 5 Solve and Check. 8(3f – 4) = 4(6f – 8)

10. Apply! Ben can buy a skateboard from a friend for $60 and rent the safety equipment for $1.50 per hour or he can rent the skateboard and safety equipment for $5.50 per hour. How many hours must you use the skateboard to justify buying it?

11. Practice! Solve and Check. 1)4 – 4y = -2(2y – 2) 2)4x – 3 = 2x +5 3)-6z + 8 = z + 10 – 7z
