Question 815267
Part I	4.00%		per annum	-------------	Amount invested =x	
Part II	6.00%		per annum	------------	Amount invested = y	
	30000					
Interest-----	1380.00					
						
Part I	4.00%		per annum	---x		
Part II	6.00%		per annum	---y		
Total investment						
x	+	1	y=	30000	-------------1	
Interest on both investments						
4.00%	x	+	6.00%	y=	1380	
Multiply by		100				
4	x	+	6	y=	138000.00	--------2
Multiply (1) by			-4			
we get						
-4	x	-4	y=	-120000.00		
Add this to (2)						
0	x	2	y=	18000		
divide by		2				
			y	=	9000	
Part I	4.00%	$	21000			
Part II	6.00%	$	9000			
						
CHECK						
21000	---------	4.00%	-------	840.00		
9000	-------------	6.00%	-------	540.00		
Total			--------------------	1380.00
