Solve the following simultaneous equations using graphical method. x + 2 y = 5; y = -2 x – 2.

The first equation is x + 2y = 5

x 1 3 5 y 2 1 0 (x,y) (1,2) (3,1) (5,0)

Now the second equation is y = - 2 x – 2

x 1 2 0 y -4 -6 -2 (x,y) (1,- 4) (2,- 6) (0, - 2)

The Point of intersection is (- 3 , 4)
