2 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 inverse operations in the reverse order of operations used in the equation.

Front

What is the first step to solve the equation 7y + 7 = -28?

Back

Subtract 7 from both sides to get 7y = -35.

Front

What is the second step to solve the equation 7y = -35?

Back

Divide both sides by 7 to find y = -5.

Front

What does it mean to perform inverse operations?

Back

Inverse operations are operations that undo each other, such as addition and subtraction or multiplication and division.

Front

How do you check your solution for a two-step equation?

Back

Substitute the solution back into the original equation to see if both sides are equal.

Front

What is the solution to the equation 5x - 7 = 13?

Back

The solution is x = 4.

Front

What is the first step to solve the equation 4y - 8 = 12?

Back

Add 8 to both sides to get 4y = 20.

Front

What is the second step to solve the equation 4y = 20?

Back

Divide both sides by 4 to find y = 5.

Front

What is the solution to the equation -24 = -2y - 6?

Back

The solution is y = 9.
