Solving Inequalities In One Variable & Graph On Number Line

Learn how to solve inequalities involving one variable and graph the solution on a number in this video math tutorial by Mario's Math Tutoring. We go through 5 examples of increasing difficulty. We discuss what happens to the inequality sign when you multiply or divide both sides of the inequality by a negative number. We discuss the importance of getting the variable on the left side of the inequality sign and tips for knowing which way to graph the inequality on the number line. Some of the examples involve working with fractions, the distributive property, and one of the examples is a special case where there is no solution.

Thank you for making these videos, they have helped me complete my math assignments.

I'm terrible at math ( hate it, especially Allegra) but this video surely helped. Understood it better in this video opposed to my teacher. Seems basic, just hard for me to memorize it on tests. Very informative video though, I'm sure helps a lot of other students.

Thank you this was very helpful! But I don’t understand why you have to flip the inequality sign when you multiply or divide.
