The document is a lesson plan on solving two-step equations involving fractions. It includes examples of solving equations with fractions on both sides, as well as word problems that can be represented by equations with fractions. The lesson outlines the rules for solving these types of equations, which are to keep the equation balanced, simplify each side, move the variable to one side using inverse operations, and then use inverse operations to solve for the variable.
