The video tutorial explains how to solve an absolute value equation involving nested absolute values. It begins by introducing the concept of absolute value equations and then demonstrates solving the outer and inner absolute values separately. The tutorial provides step-by-step solutions and concludes with a graphical verification using Desmos to confirm the solutions.
