Two Step Equations

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable. For example, in the equation 2x + 3 = 11, you would first subtract 3 and then divide by 2.

Front

How do you isolate a variable in an equation?

Back

You perform inverse operations to both sides of the equation until the variable is alone.

Front

Back

Subtract 11 from both sides to get -3x = 33, then divide by -3 to find x = -11.

Front

Back

Add 12 to both sides to get -2x = -18, then divide by -2 to find x = 9.
