Question 568311
-3x-2y	=	6	.............1	
3x-y	=	12	.............2	

equation1								
when x=	0,	y=-3(0,-3)
when y =	0,x=-2(-2,0)
Equation 2								
when x=	0,y=-12	(0,-12)
when y =0,x=4(4,0)

Plot these points and draw the lines.
The point of intersection is the solution of the system.

{{{drawing(300,300,-15,10,-10,10,circle(0,-3,0.3),circle(-2,0,0.3),circle(0,-12,0.3),circle(4,0,0.3),grid(1),graph(300,300,-15,10,-10,10,y=-(3/2)x-3,y=3x-12))}}}

The solution is (2,-6)
