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

What is the first step to solve the equation 2x - 3 = 1?

Back

Add 3 to both sides of the equation.

Front

What is the second step to solve the equation 2x - 3 = 1 after adding 3?

Back

Divide both sides by 2.

Front

Solve the equation: 2x - 3 = 1

Back

x = 2

Front

What is the first step to solve the equation 2x - 7 = -23?

Back

Add 7 to both sides of the equation.

Front

What is the second step to solve the equation 2x - 7 = -23 after adding 7?

Back

Divide both sides by 2.

Front

Back

x = -8

Front

What is the first step to solve the equation 12 - 6y = 24?

Back

Subtract 12 from both sides of the equation.

Front

What is the second step to solve the equation 12 - 6y = 24 after subtracting 12?

Back

Divide both sides by -6.

Front

Solve the equation: 12 - 6y = 24

Back

y = -2
