The video tutorial explains how to solve a system of three linear equations with three unknowns using the elimination method. It discusses the three possible outcomes: one solution, no solution, or an infinite number of solutions. The tutorial uses graphical representations to illustrate these outcomes and provides a detailed step-by-step process for eliminating variables. It concludes by explaining how to express solutions parametrically when there are infinite solutions, using a new variable to relate x, y, and z. The video emphasizes the importance of understanding the relationships between variables to find solutions.
