The video tutorial covers solving word problems using systems of equations. It begins with an introduction to the topic, explaining the steps involved in solving such problems. The tutorial then discusses graphical and algebraic solutions, followed by three detailed examples: a swimming practice problem, a rectangle perimeter problem, and a ticket purchase problem. Each example demonstrates the use of the substitution method to find solutions, emphasizing the importance of identifying variables, setting up equations, and drawing conclusions.
