2	x		-1	y	=	4	.............1	
								
3	x		-2	y	=	7	.............2	
Eliminate	y							
multiply (1)by		-2						
Multiply (2) by		1						
-4	x		2	y	=	-8		
3	x		-2	y	=	7		
Add the two equations								
-1	x				=	-1		
/	-1							
x	=	1						
plug value of			x	in (1)				
2	x		-1	y	=	4		
2			-1	y	=	4		
			-1	y	=	4		-2
			-1	y	=	2		
				y	=	-2		
x=	1						
y=	-2
