Solving Two-Step Inequalities and Graphing Techniques

The video tutorial covers solving two-step inequalities, emphasizing the importance of flipping the inequality symbol when multiplying or dividing by a negative number. It provides multiple examples, demonstrating step-by-step solutions and explaining when to flip the symbol. The tutorial also discusses graphing solutions on a number line, using open or closed circles, and determining the direction of shading. Viewers are encouraged to practice the examples independently and engage with the content by liking, commenting, and sharing.

What should you do to the inequality symbol when you multiply or divide both sides by a negative number?

• Subtract 1 from it

• Leave it unchanged

• Flip it

• Add 1 to it
