Solving 2-step Equations

Front

What is a 2-step equation?

Back

A 2-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

How do you isolate a variable in a 2-step equation?

Back

To isolate a variable, perform the inverse operations in the reverse order of how they appear in the equation.

Front

What is the first step to solve the equation 4m + 12 = 16?

Back

Subtract 12 from both sides to get 4m = 4.

Front

What is the second step to solve the equation 4m + 12 = 16?

Back

Divide both sides by 4 to find m = 1.

Front

Solve the equation: 8s - 10 = 6.

Back

s = 2.

Front

What is the first step to solve the equation 7x + 5 = 40?

Back

Subtract 5 from both sides to get 7x = 35.

Front

What is the second step to solve the equation 7x + 5 = 40?

Back

Divide both sides by 7 to find x = 5.

Front

Solve the equation: 10p + 7 = 17.

Back

p = 1.

Front

What is the first step to solve the equation 2x - 18 = 34?

Back

Add 18 to both sides to get 2x = 52.

Front

What is the second step to solve the equation 2x - 18 = 34?

Back

Divide both sides by 2 to find x = 26.
