x		Investment in Fund I	
y		Investment in Fund II	
Interest calculation in the two repective years.
0.09x+0.03y= 900...............(1)
0.10x+0.01y =860...............(2)

Multiply both equations by 100 to eliminate decimals

9	x	+	3	y	=	90000	.............1	
								
10	x	+	1	y	=	86000	.............2	
Eliminate	y							
multiply (1)by		1						
Multiply (2) by		-3						
9	x		3	y	=	90000		
-30	x		-3	y	=	-258000		
Add the two equations								
-21	x				=	-168000		
/	-21							
x	=	8000						
plug value of			x	in (1)				
9	x	+	3	y	=	90000		
72000		+	3	y	=	90000		
			3	y	=	90000-72000
			3	y	=	18000		
				y	=	6000		
$	8000		Investment in Fund I					
$	6000		Investment in Fund II
