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 -15 = -4y + 5?

Back

Subtract 5 from both sides to get -20 = -4y.

Front

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

Back

Divide both sides by -4 to find y = 5.

Front

What is the solution to the equation 2n + 10 = -2?

Back

The solution is n = -6.

Front

What is the first step to solve the equation 2n + 10 = -2?

Back

Subtract 10 from both sides to get 2n = -12.

Front

What is the second step to solve the equation 2n = -12?

Back

Divide both sides by 2 to find n = -6.

Front

How do you solve the equation -4 = 2t - 2?

Back

Add 2 to both sides to get -2 = 2t, then divide by 2 to find t = -1.

Front
