Question 937965
1	x		-9	y	=	8	.............1	
								
3	x	+	1	y	=	-60	.............2	
Eliminate	y							
multiply (1)by		1						
Multiply (2) by		9						
1	x		-9	y	=	8		
27	x	+	9	y	=	-540		
Add the two equations								
28	x				=	-532		
/	28							
x	=	-19						
plug value of			x	in (1)				
1	x		-9	y	=	8		
-19			-9	y	=	8		
			-9	y	=	8	+	19
			-9	y	=	27		
				y	=	-3		1
x=	-19					
y=	-3
