Part I	7.00%		per annum	-------------	Amount invested =x		
Part II	8.50%		per annum	------------	Amount invested = y		
	11000						
Interest-----	860.00						
							
Part I	7.00%		per annum	---x			
Part II	8.50%		per annum	---y			
Total investment							
x	+	1	y=	11000	-------------1		
Interest on both investments							
7.00%	x	+	8.50%	y=	860		
Multiply by		100					
7	x	+	8.5	y=	86000.00	--------2	
Multiply (1) by			-7				
we get							
-7	x	-7	y=	-77000.00			
Add this to (2)							
0	x	1.5	y=	9000			
divide by		1.5					
			y	=	6000		
Part I	7.00%	$	5000				
Part II	8.50%	$	6000				
							
CHECK							
5000	---------	7.00%	-------	350.00
