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: x/12 - 8 = -4

Back

x = 48

Front

What is the first step to solve the equation 2s - 4 = 6?

Back

Add 4 to both sides to isolate the term with the variable.

Front

Solve: 2s - 4 = 6

Back

s = 5

Front

What is the purpose of isolating the variable in an equation?

Back

To find the value of the variable that makes the equation true.

Front

Solve: 9 + 3x = 10

Back

x = 1/3

Front

What is the second step to solve the equation 11b + 7 = 40?

Back

Subtract 7 from both sides to isolate the term with the variable.

Front

Solve: 11b + 7 = 40

Back

b = 3

Front

What does it mean to 'isolate the variable'?

Back

To manipulate the equation so that the variable is alone on one side.

Front

Solve: 7 + a/3 = 5

Back

a = -6
