The video tutorial covers solving inequalities using addition and subtraction. It explains how to isolate variables, perform inverse operations, and graph solutions on a number line. The tutorial includes examples with both positive and negative numbers, emphasizing the importance of rewriting subtraction as addition when dealing with integers. The lesson concludes with a recap of the steps involved in solving inequalities.
