The document provides instruction on solving multi-step equations using the distributive property. It begins with an objective and rules for solving equations. It then works through examples of distributing terms in parentheses and isolating variables. The examples become increasingly complex. It concludes with having students trade and solve equations with a partner.

Trade an Equation
With your partner, create an equation that involves parenthesis.
You will then trade your equation with the other partnership and
solve their equation.
