Question 590890
1	x	+	1	y	=	-5	.............1	
4	x		-3	y	=	8	.............2	
Eliminate	y							
multiply (1)by		3						
Multiply (2) by		1						
3	x		3	y	=	-15		
4	x		-3	y	=	8		
Add the two equations								
7	x				=	-7		
/	7							
x	=	-1      						
plug value of			x	in (1)				
1	x	+	1	y	=	-5		
-1    		+	1	y	=	-5		
			1	y	=	-5+1      
			1	y	=	-4      		
				
(-1,-4)

-2x+(1/2)y=1  
multiply by 2
-4x+y=2..............(1)  
2x+y=14..............(2)


-4	x	+	1	y	=	2	.............1	
2	x	+	1	y	=	14	.............2	
Eliminate	y							
multiply (1)by		-1						
Multiply (2) by		1						
4	x		-1	y	=	-2		
2	x	+	1	y	=	14		
Add the two equations								
6	x				=	12		
/	6							
x	=	2      						
plug value of			x	in (1)				
-4	x	+	1	y	=	2		
-8    		+	1	y	=	2		
			1	y	=	2	+	8      
			1	y	=	10      		
				y	=	10
