Cross Multiplication Method for Solving Pair of Linear Equations

This video tutorial covers solving a system of linear equations using the elimination method. The instructor introduces the problem, presents the equations, and demonstrates how to prepare them for elimination by adjusting coefficients. The tutorial then walks through solving for x by eliminating y, followed by substituting the value of x to find y. The session concludes with a recap of the steps taken to arrive at the solution, which is x = 1/2 and y = 1/3.
