What is the first step to solve the equation 3x + 2 = 11?

Back

Subtract 2 from both sides to get 3x = 9.

Front

What is the second step to solve the equation 3x = 9?

Back

Divide both sides by 3 to get x = 3.

Front

What does it mean to 'balance' an equation?

Back

Balancing an equation means keeping both sides equal by performing the same operation on both sides.
