The video tutorial covers solving one-variable equations, specifically focusing on a problem from the 2016 released STAR test. The instructor explains how to represent the problem using a model, set up the equation, and solve it by isolating the variable. The solution is verified by plugging it back into the equation. The tutorial emphasizes keeping variables positive and using inverse operations to maintain balance in the equation.
