How to solve and graph one variable inequalities

The video tutorial explains how to solve and graph one-variable inequalities. It covers the step-by-step process of simplifying equations, identifying and isolating variables, and using inverse operations. The tutorial also highlights the importance of flipping the inequality sign when multiplying or dividing by a negative number. Additionally, it discusses graphing solutions on a number line, determining open or closed points, and shading the correct region to represent the solution set.
