Solving One-Step Inequalities and Graphing Solutions

This video tutorial covers solving inequalities using inverse operations, emphasizing the importance of flipping the inequality symbol when multiplying or dividing by a negative number. It provides step-by-step examples of solving inequalities through addition, subtraction, multiplication, and division, and demonstrates how to graph solutions on a number line. The tutorial also includes advanced examples to reinforce understanding.

What must you do when you multiply or divide both sides of an inequality by a negative number?

• Square both sides

• Flip the inequality symbol

• Do nothing to the inequality symbol

• Add 1 to both sides
