Assignment: Problem Set: Combining Like Terms
Solve the equations by combining like terms. Show all the steps.
Then write two of your own problems where you combine like terms. Show all steps, as well as
your solution.

4x + x – 8 = 7
(combine like terms)
5x – 8 = 7
(add 8 on both sides)
5x –8 + 8 = 7 + 8
5x = 15
(divide both sides by 5)
5x ÷ 5 = 15 ÷ 5
X = 3
5. 8 = 3(3 x + 8) − x
8 = 3(3x + 8) - x
(use distributive property)
(3 x 3x) + (3 x 8) - x = 8
9x + 24 + -x = 8
(9x + -x) + (24)
(combine like terms)
