Back

Add 4 to both sides to find x = 6.

Front

What is the importance of performing the same operation on both sides of an equation?

Back

Performing the same operation on both sides maintains the equality of the equation.

Front

How do you check your solution for a two-step equation?

Back

Substitute the solution back into the original equation to verify that both sides are equal.
