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

Solve: 3c + 5 = 23

Back

c = 6

Back

x = 12

Front

What does it mean to isolate a variable in an equation?

Back

To isolate a variable means to get the variable alone on one side of the equation.

Front

Solve: 4x + 7 = 23

Back

x = 4

Front

What is the second step to solve the equation 3x - 7 = 32?

Back

Add 7 to both sides after isolating the term with the variable.

Front

Solve: 3x - 7 = 32

Back

x = 13

Front

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations are used to undo operations and isolate the variable.
