The video tutorial covers systems of equations, focusing on graphing and substitution methods. It explains the three types of solutions: one solution, no solution, and infinite solutions. The tutorial provides examples and practice problems to illustrate these concepts, emphasizing the importance of understanding special cases in systems of equations.
