Front

What is an equation with variables on both sides?

Back

An equation where the variable appears on both the left and right sides.

Front

What does it mean to isolate a variable?

Back

To manipulate an equation so that the variable is on one side and all other terms are on the other.

Front

What is the first step in solving the equation 5x + 3 = 2x + 12?
