Finding the value of x using a trapezoid alternate interior angles and corresponding

The video tutorial explains how to solve for variables X and Y using properties of supplementary angles and parallel lines. It begins by identifying the problem of having two variables in one equation and the need to create a solvable equation. The instructor extends parallel lines to identify alternate interior and corresponding angles, using these properties to solve for X and Y. The tutorial emphasizes the importance of understanding definitions and common mistakes in solving equations.
