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 the inverse operations in the reverse order of how they appear in the equation.

Front

Solve for x: 5x + 4 = 64

Back

x = 12

Front

Solve for x: 4x + 1 = 21

Back

x = 5

Front

Solve for x: 2x - 3 = 1

Back

x = 2

Front

Solve for p: 6p - 5 = 13

Back

p = 3

Front

Solve for w: 6w - 1 = 11

Back

w = 2

Front

What is the first step to solve the equation 5x + 4 = 64?

Back

Subtract 4 from both sides to get 5x = 60.

Front

What is the second step to solve the equation 5x = 60?

Back

Divide both sides by 5 to get x = 12.

Front

What does it mean to perform the inverse operation?

Back

An inverse operation reverses the effect of the original operation, such as addition and subtraction or multiplication and division.
