The video tutorial explains how to solve simultaneous equations involving a linear equation and an equation with square roots. Traditional methods like substitution and elimination are ineffective, so the video demonstrates manipulating the equations using the difference of squares. This approach allows the equations to be rewritten in a solvable form, leading to the solution of the variables X and Y.
