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 the reverse order of how they appear in the equation.

Front

What is the first step to solve the equation -3y + 5 = 32?

Back

Subtract 5 from both sides to get -3y = 27.

Front

What is the second step to solve the equation -3y + 5 = 32?

Back

Divide both sides by -3 to find y = -9.

Front

What does it mean to 'undo' an operation in solving equations?

Back

'Undoing' an operation means performing the opposite operation to isolate the variable.

Front

What is the solution to the equation -5x - 6 = 39?

Back

The solution is x = -9.

Front

How do you check if your solution to a two-step equation is correct?

Back

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

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 + 7 = -28?

Back

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

Front

What is the solution to the equation 7 + 7x = -14?

Back

The solution is x = -3.
