Part I	6.00%		per annum	-------------	Amount invested =x		
Part II	9.00%		per annum	------------	Amount invested = y		
	30000						
Interest-----	1980.00						
							
Part I	6.00%		per annum	---x			
Part II	9.00%		per annum	---y			
Total investment							
x	+	1	y=	30000	-------------1		
Interest on both investments							
6.00%	x	+	9.00%	y=	1980		
Multiply by		100					
6	x	+	9	y=	198000.00	--------2	
Multiply (1) by			-6				
we get							
-6	x	-6	y=	-180000.00			
Add this to (2)							
0	x	3	y=	18000			
divide by		3					
			y	=	6000		
Part I	6.00%	$	24000				
Part II	9.00%	$	6000				
							
CHECK							
24000	---------	6.00%	-------	1440.00
