The video tutorial covers solving systems of equations and inequalities. It begins with an introduction to what these systems are, followed by examples and solutions using Desmos. The tutorial explains how to graph systems of equations to find intersection points, which represent solutions. It then transitions to systems of inequalities, explaining how to identify solutions through overlapping shaded areas on graphs. The video provides step-by-step instructions and encourages viewers to practice using Desmos.

What is a system of equations?

• A single equation with multiple variables

• Two or more equations on the same graph
