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 are applied.

Front

What is the first step to solve the equation 13 = 5m - 2?

Back

Add 2 to both sides to get 15 = 5m.

Front

What is the second step to solve the equation 15 = 5m?

Back

Divide both sides by 5 to find m = 3.

Front

Solve the equation 3c + 5 = 23.

Back

c = 6.

Front

What is the first step to solve the equation 3x - 7 = 32?

Back

Add 7 to both sides to get 3x = 39.

Front

What is the second step to solve the equation 3x = 39?

Back

Divide both sides by 3 to find x = 13.

Front

Solve the equation 4(2x + 3) = 28.

Back

x = 2.

Front

What is the first step to solve the equation 3(5x - 4) = 18?

Back

Divide both sides by 3 to get 5x - 4 = 6.

Front

What is the second step to solve the equation 5x - 4 = 6?

Back

Add 4 to both sides to find 5x = 10.
