Question 875646
Part I	12.00%		per annum	-------------	Amount invested =x	
Part II	8.00%		per annum	------------	Amount invested = y	
	9000					
Interest-----	1000.00					
						
Part I	12.00%		per annum	---x		
Part II	8.00%		per annum	---y		
Total investment						
x	+	1	y=	9000	-------------1	
Interest on both investments						
12.00%	x	+	8.00%	y=	1000	
Multiply by		100				
12	x	+	8	y=	100000.00	--------2
Multiply (1) by			-12			
we get						
-12	x	-12	y=	-108000.00		
Add this to (2)						
0	x	-4	y=	-8000		
divide by		-4				
			y	=	2000	
Part I	12.00%	$	7000			
Part II	8.00%	$	2000			
						
CHECK						
7000	---------	12.00%	-------	840.00		
2000	-------------	8.00%	-------	160.00		
Total			--------------------	1000.00
