The video tutorial covers solving two-step equation word problems using real-world examples. It begins with an introduction to two-step equations and proceeds with five examples: buying a coffee mug and refills, purchasing water bottles and pizza, buying shirts with a discount coupon, calculating temperature decrease, and determining the descent time of a submarine. Each example demonstrates how to define variables, identify constants, and solve equations efficiently.
