The system of equations 2x + 3y = 6 and 2x + y = -2 has to be solved graphically. The two equations represents a set of straight lines. The coordinates of their point of intersection is the required solution.

It is seen that the lines intersect at the point (-3, 4)

The solution of the set of equations is x = -3 and y = 4

Lets use the method of elimination.
   2x + 3y = 6
-- 2x + y = -2
-------------------
2y = 8
y = 4

2x + 4 = -2
2x = -6
x = -3
