Linear equations in one variable worksheet

Show the same operation on both sides at each step. Substitute your answer back into the original equation.

Name ________________________Date ______________

Worked example · Solve 4x + 3 = 2x + 15

How can you collect all the x terms on one side?

Subtract 2x from both sides to get 2x + 3 = 15.

Subtract 3 to get 2x = 12. Divide both sides by 2 to find x = 6.
