Solving One Step Inequalities: Addition and Subtraction Techniques

The video tutorial covers solving one-step inequalities using addition and subtraction. It explains the steps to isolate the variable, the importance of inverse operations, and how to check and graph solutions. Several examples are provided, including those with negative numbers and a word problem, to illustrate the concepts. The tutorial emphasizes the need to verify solutions before graphing and provides practice problems to reinforce learning.
