Question 805514
Part I	8.00%		per annum	-------------	Amount invested =x	
Part II	9.00%		per annum	------------	Amount invested = y	
	10000					
Interest-----	830.00					
						
Part I	8.00%		per annum	---x		
Part II	9.00%		per annum	---y		
Total investment						
x	+	1	y=	10000	-------------1	
Interest on both investments						
8.00%	x	+	9.00%	y=	830	
Multiply by		100				
8	x	+	9	y=	83000.00	--------2
Multiply (1) by			-8			
we get						
-8	x	-8	y=	-80000.00		
Add this to (2)						
0	x	1	y=	3000		
divide by		1				
			y	=	3000	 -
Part I	8.00%	$	7000			
Part II	9.00%	$	3000			
						
CHECK						
7000	---------	8.00%	-------	560.00		
3000	-------------	9.00%	-------	270.00		
Total			--------------------	830.00
