Solving One and Two Step Inequalities Challenge

The video tutorial covers solving one and two-step inequalities using addition, subtraction, multiplication, and division. It explains the concept of equivalent inequalities and the importance of flipping the inequality sign when multiplying or dividing by a negative number. The tutorial includes examples and graphing solutions, as well as application problems to demonstrate real-world uses of inequalities.

What is an equivalent inequality?

• An inequality with only positive solutions

• An inequality with different solutions

• An inequality with no solutions

• An inequality with the same solutions
