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

2x - 3y – 6 = 0; 2x + y + 10 = 0

Answer :

2x - 3y - 6 = 0

⇒ 3y = 2x - 6

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 + y + 10 = 0

⇒ y = - (2x + 10)

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.

The point of intersection is ( - 3, - 4)
