Solving 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 3n + 4 = 7?

Back

Subtract 4 from both sides to get 3n = 3.

Front

What is the second step to solve the equation 3n = 3?

Back

Divide both sides by 3 to find n = 1.

Front

Solve for c: 4c - 6 = 2.

Back

c = 2.

Front

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

Back

Add 6 to both sides to get 4c = 8.

Front

What is the second step to solve the equation 4c = 8?

Back

Divide both sides by 4 to find c = 2.

Front

Solve for k: 2k + 12 = -4.

Back

k = -8.

Front

What is the first step to solve the equation 2k + 12 = -4?

Back

Subtract 12 from both sides to get 2k = -16.

Front

What is the second step to solve the equation 2k = -16?

Back

Divide both sides by 2 to find k = -8.
