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 7y + 3 = 25?

Back

Subtract 3 from both sides of the equation to isolate the term with the variable.

Front

What is the solution to the equation 7y + 3 = 25?

Back

y = 3.

Front

How do you solve the equation (p/7) - 3 = 8?

Back

First, add 3 to both sides, then multiply both sides by 7 to isolate p.

Front

What is the solution to the equation (p/7) - 3 = 8?

Back

p = 77.

Front

What is the first step to solve the equation 8s + 1 = 33?

Back
