Solving Linear Equations by Graphical Method: Finding the Number of Solutions for Parallel Lines

The video tutorial explains how to solve a pair of linear equations using the graphical method. It begins by introducing the problem and the equations to be solved. The tutorial then demonstrates how to plot each equation on a graph, using specific values for X and Y to find points on the lines. After plotting both equations, it is shown that the lines are parallel and do not intersect, indicating no common solutions. The tutorial concludes by explaining how the coefficients of the equations can predict the parallel nature of the lines without graphing.
