Solve 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

What is the first step to solve the equation 8m - 5.5 = 10.1?

Back

Add 5.5 to both sides of the equation.

Front

What is the second step to solve the equation 8m - 5.5 = 10.1 after adding 5.5?

Back

Divide both sides by 8.

Front

Solve for x: 3x + 1 = 10.

Back

x = 3.

Front

What is the first step to solve the equation 8/11(n - 10) = 64?

Back

Multiply both sides by 11/8.

Front

What is the second step to solve the equation 8/11(n - 10) = 64 after multiplying?

Back

Add 10 to both sides.

Front

Solve for s: -8s + 1 = 33.

Back

s = -4.

Front

What is the first step to solve the equation -7(z - 6) = -70?

Back

Divide both sides by -7.

Front

What is the second step to solve the equation -7(z - 6) = -70 after dividing?

Back

Add 6 to both sides.
