Solving 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.

Front

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

Back

To isolate a variable, perform inverse operations in the reverse order of operations.

Front

What is the first step to solve the equation 3n + 4 = 7?

Back

Subtract 4 from both sides to get 3n = 3.

Front

What is the second step to solve the equation 3n = 3?

Back

Divide both sides by 3 to find n = 1.

Front

Solve the equation: -4 = 2t - 2. What is t?

Back

t = -1.

Front

What does it mean to perform inverse operations?

Back

Inverse operations are operations that undo each other, such as addition and subtraction or multiplication and division.
