Solve graphically the set of equations: 2x+3y = 6, 2x+y = -2
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
