Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

How do you isolate a variable in a two-step equation?

Back

To isolate a variable, perform the inverse operations in the reverse order of how they appear in the equation.

Back

y = 5

Front

What is the first step to solve the equation 3x + 4 = 10?

Back

Subtract 4 from both sides to get 3x = 6.

Front

What is the second step to solve the equation 3x = 6?

Back

Divide both sides by 3 to get x = 2.

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.
