Solving and Graphing One Step Inequalities

This video tutorial covers solving and graphing one-step inequalities. It begins with an introduction to inequalities, explaining that the process is similar to solving equations. The tutorial then demonstrates solving inequalities using addition, subtraction, multiplication, and division. It also covers graphing inequalities, explaining the use of open and closed circles to represent solutions. The video concludes with practice problems and solutions to reinforce the concepts taught.
