Solve Single-Step Equations

Front

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

Back

To isolate a variable means to manipulate the equation so that the variable is on one side of the equation by itself.

Front

Solve the equation: x + 7 = 12

Back

x = 5

Front

Solve: y - 14 = 66

Back

y = 80

Front

Back

y = 12

What is the first step to solve the equation: x - 3 = 5?

Back

Add 3 to both sides of the equation.

Front

Solve: 5y = 25

Back

y = 5

Front

What operation would you use to solve the equation: z/4 = 3?

Back

Multiply both sides by 4.

Front

Solve: 2x + 6 = 14

Back

x = 4
