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 the inverse operations in reverse order: first eliminate the constant term, then the coefficient of the variable.

Front

What is the first step to solve the equation 2x + 9 = -3?

Back

Subtract 9 from both sides to isolate the term with the variable: 2x = -3 - 9.

Front

What is the solution to the equation 2x + 9 = -3?

Back

The solution is x = -6.

Front

How do you solve the equation 7y + 7 = -28?

Back

First, subtract 7 from both sides to get 7y = -28 - 7, then divide by 7.

Front

What is the solution to the equation 7y + 7 = -28?

Back

The solution is y = -5.

Front

What is the second step to solve the equation 9x + 10 = 91?

Back

First, subtract 10 from both sides to get 9x = 91 - 10, then divide by 9.

Front

What is the solution to the equation 9x + 10 = 91?

Back

The solution is x = 9.

Front

How do you solve the equation -2x - 10 = 6?

Back

First, add 10 to both sides to get -2x = 6 + 10, then divide by -2.

Front

What is the solution to the equation -2x - 10 = 6?

Back

The solution is x = -8.
