Question 559409
3x+2y=-9	.............1	
-10x+5y	=-5	.............2	
Eliminate y								
multiply (1)by 		-5						
Multiply (2) by		2						
-15x-10y=45		
-20x+10	y=-10		
Add the two equations								
-35x=35		
/	-35							
x	=	-1 			
plug value of 			x	in (1)				
3	x	+	2	y	=	-9		
-3		+	2	y	=	-9		
			2	y	=	-9	+	3
			2	y	=	-6		
				y	=	-3
