http://www.freemathvideos.com In this video series I show you how to solve a system of equations by graphing. When solving a system of equations by graphing we graph each equation separately and then analyze where the two lines intersect or if at all. If the two lines intersect at a point then the values of the x and y coordinates are our solution of the system. If our graphs are the same line then we have infinite many solutions and if the graphs are parallel and never intersect then we have no solution.
x + y = 3 , 3x 2y = 4
