Solving 1-Step Inequalities with Addition and Subtraction

The video tutorial covers solving inequalities using addition and subtraction, emphasizing that the process is similar to solving equations. It explains how to graph inequalities on a number line, using open and closed circles to represent different inequality signs. The tutorial includes examples and practice problems to reinforce the concepts, ensuring students understand the importance of using the correct inequality sign and graphing accurately.

What is the main difference between solving equations and inequalities?

• The steps are different.

• You need to graph the solution for inequalities.

• Inequalities do not have solutions.

• You use different mathematical operations.
