Part I	4.00%		per annum	-------------	Amount invested =x	
Part II	9.00%		per annum	------------	Amount invested = y	
	8000					
Interest-----	570.00					
						
Part I	4.00%		per annum	---x		
Part II	9.00%		per annum	---y		
Total investment						
x	+	1	y=	8000	-------------1	
Interest on both investments						
4.00%	x	+	9.00%	y=	570	
Multiply by		100				
4	x	+	9	y=	57000.00	--------2
Multiply (1) by			-4			
we get						
-4	x	-4	y=	-32000.00		
Add this to (2)						
0	x	5	y=	25000		
divide by		5				
			y	=	5000	
Part I	4.00%	$	3000			
Part II	9.00%	$	5000			
						
CHECK						
3000	---------	4.00%	-------	120.00
