Help! I am in 7th grade Hel! In this unit, you solved two-step equations. A two-step equation is an equation of the form px + q = r. It takes two steps to solve for the variable x. For example, 3x + (-5) = 19 is a two-step equation. How could you transform this particular equation to create a three-step equation? List several ways you could transform it using common math operations.

Next, try solving one of the three-step equations you created for x. (Use a guess and check strategy, if necessary.) What additional step was required to find the solution? In your opinion, is solving a three-step equation more difficult than solving a two-step equation? Why or why not? Do you think there is a limit to the number of steps it takes to solve an equation? Explain.
