An equation with variables on both sides has an x term to the left and to the right of the equal sign, so the first job is to gather the x terms on one side. There are 5 sheets for 8th grade here, each with an answer key. Solve Equations With Variables on Both Sides begins with 5x + 6 = 2x + 21, Distribute on Both Sides, Then Solve adds parentheses, and Both-Sides Equations With Fractions and Parentheses runs two pages. Find the Error When Moving Terms Across closes the set. The sheets practice 8.EE.C.7.B.

Frequently Asked Questions

Add or subtract one of the x terms from both sides so x is on only one side. Then move the numbers to the other side and divide. For 5x + 6 = 2x + 21, subtract 2x to get 3x + 6 = 21, so x = 5.
