The video tutorial by Miss Travis covers lesson 2.4 on solving multi-step inequalities. It begins with an introduction to the topic and outlines the learning targets. The tutorial includes several examples demonstrating how to solve inequalities, graph them, and use interval notation. It also covers solving inequalities with variables on both sides and addresses true and false statements. The lesson concludes with a real-life application problem and instructions for assignments.

What is the learning target for this lesson?

• Solving single-step equations

• Writing and solving multi-step inequalities

• Understanding quadratic functions

• Graphing linear equations
