Question 667675
Part I	8.00%		per annum	-------------	Amount invested =x	
Part II	9.00%		per annum	------------	Amount invested = y	
	5000					
Interest-----	440					
						
Part I	8.00%		per annum	---x		
Part II	9.00%		per annum	---y		
Total investment						
x	+	1	y=	5000	-------------1	
Interest on both investments						
8.00%	x	+	9.00%	y=	440	
Multiply by		2				
8	x	+	9	y=	44000.00	--------2
Multiply (1) by			-8			
we get						
-8	x	-8	y=	-40000.00		
Add this to (2)						
0	x	1	y=	4000		
divide by		1				
			y	=	4000	
Part I	8.00%	$	1000			
Part II	9.00%	$	4000			
						
CHECK						
1000	---------	8.00%	-------	80.00		
4000	-------------	9.00%	-------	360.00		
Total			--------------------	440.00
