Q21 of 102 Page 49

Find the solution of the following simultaneous equations of graphical method:

2x + y – 3 = 0; 2x–3y–7 = 0

2x + y - 3 = 0


⇒ y = 3 - 2x


Now we need to plot this equation on graph, for that we will take some points of x and put in the equation to obtain points of y.



2x - 3y - 7 = 0


⇒ 3y = 2x - 7



Now we need to plot this equation on graph, for that we will take some points of x and put in the equation to obtain points of y.
