Part I	3.50%		per annum	-------------	Amount invested =x		
Part II	5.00%		per annum	------------	Amount invested = y		
	18000						
Interest-----	750.00						
							
Part I	3.50%		per annum	---x			
Part II	5.00%		per annum	---y			
Total investment							
x	+	1	y=	18000	-------------1		
Interest on both investments							
3.50%	x	+	5.00%	y=	750		
Multiply by		100					
3.5	x	+	5	y=	75000.00	--------2	
Multiply (1) by			-3.5				
we get							
-3.5	x	-3.5	y=	-63000.00			
Add this to (2)							
0	x	1.5	y=	12000			
divide by		1.5					
			y	=	8000		
Part I	3.50%	$	10000				
Part II	5.00%	$	8000				
							
CHECK							
10000	---------	3.50%	-------	350.00			
8000	-------------	5.00%	-------	400.00
