This document provides instruction and examples for solving two-step inequalities. It begins with a bellwork problem and objective to introduce solving two-step inequalities. It then provides examples of solving various two-step inequalities step-by-step. These include solving for variables like y and x, as well as setting up and solving word problems involving inequalities. The final section directs students to practice similar problems on page 375, problems 4 through 15 of their homework.
