Question 547672
6x+12y=-6 
/6
x+2y=-1

and 2x+5y=0

1	x	+	2	y	=	-1	.............1	
2	x	+	5	y	=	0	.............2	
Eliminate 	y							
multiply (1)by 		-5						
Multiply (2) by		2						
-5	x		-10	y	=	5		
4	x	+	10	y	=	0		
Add the two equations								
-1	x				=	5.00		
/	-1							
x	=	-5      						
plug value of 			x	in (1)				
1	x	+	2	y	=	-1		
-5		+	2	y	=	-1		
			2	y	=	-1	+	5
			2	y	=	4		
				y	=	2
