Question 582736
8	x	+	1	y	=	-9	.............1	
-9	x		-1	y	=	7	.............2	
Eliminate	y							
multiply (1)by		1						
Multiply (2) by		1						
8	x		1	y	=	-9		
-9	x		-1	y	=	7		
Add the two equations								
-1	x				=	-2		
/	-1							
x	=	2      						
plug value of			x	in (1)				
8	x	+	1	y	=	-9		
16    		+	1	y	=	-9		
			1	y	=	-9		-16      
			1	y	=	-25      		
				y	=	-25
