8%------------- x
9%---------------y

x+y = 51000................(1)
0.08x=0.09y
8x=9y 
8x-9y=0.....................(2)
Eliminate	y							
multiply (1)by		9						
Multiply (2) by		1						
9	x	\	9	y	=	459000		
8	x		-9	y	=	0		
Add the two equations								
17	x				=	459000		
/	17							
x	=	27000						
plug value of			x	in (1)				
1	x	+	1	y	=	51000		
27000		+		y	=	51000		
				y	=	51000		-27000
				y	=	24000		
				y	=	24000		
	$27000--------	8%					
	$24000-------	9%
