Part I	4.00%		per annum	-------------	Amount invested =x		
Part II	8.00%		per annum	------------	Amount invested = y		
	6000						
Interest-----	400.00						
							
Part I	4.00%		per annum	---x			
Part II	8.00%		per annum	---y			
Total investment							
x	+	1	y=	6000	-------------1		
Interest on both investments							
4.00%	x	+	8.00%	y=	400		
Multiply by		100					
4	x	+	8	y=	40000.00	--------2	
Multiply (1) by			-4				
we get							
-4	x	-4	y=	-24000.00			
Add this to (2)							
0	x	4	y=	16000			
divide by		4					
			y	=	4000		
Part I	4.00%	$	2000				
Part II	8.00%	$	4000				
							
CHECK							
2000	---------	4.00%	-------	80.00			
4000	-------------	8.00%	-------	320.00
