The video tutorial explains two methods to solve absolute value equations involving two absolute values. It demonstrates solving the equations X - 3 = 2x + 10 and X - 3 = -2x - 10 separately, providing step-by-step instructions. The solutions are verified by substituting them back into the original equations. The tutorial concludes with a brief mention of a related video for solving equations with one absolute value.
