Part I	6.50%		per annum	-------------	Amount invested =x			
Part II	9.00%		per annum	------------	Amount invested = y			
	15000							
Interest-----	1200.00							
								
Part I	6.50%		per annum	---x				
Part II	9.00%		per annum	---y				
Total investment								
x	+	1	y=	15000	-------------1			
Interest on both investments								
6.50%	x	+	9.00%	y=	1200			
Multiply by		100						
6.5	x	+	9	y=	120000.00	--------2		
Multiply (1) by			-6.5					
we get								
-6.5	x	-6.5	y=	-97500.00				
Add this to (2)								
0	x	2.5	y=	22500				
divide by		2.5						
			y	=	9000			
Part I	6.50%	$	6000					
Part II	9.00%	$	9000					
								
CHECK								
6000	---------	6.50%	-------	390.00				
9000	-------------	9.00%	-------	810.00
