Question 562757
10x+11y	=-26.5	.............1			
5y=-27.5-20x	---------2			
/	5	=								
y=-5.5-4x				
Substitute y in 		(1)								
10x+11(	-5.5-4x)=-26.5
10	x		-60.5	+	-44	x	=	-26.5		
10	x		-44	x	=	-26.5	60.5			
-34	x	=	34							
/	-34									
x=	-1									
Plug the value of x in (1)										
10	x	+	11	y	=	-26.5				
10	*	-1	+	11	y	=	-26.5			
-10	+	11	y	=	-26.5					
11	y	=	-16.5							
/	11									
y=	-1.5
