Part I	8.00%		per annum	-------------	Amount invested =x	
Part II	7.00%		per annum	------------	Amount invested = y	
	7000					
Interest-----	500					
						
Part I	8.00%		per annum	---x		
Part II	7.00%		per annum	---y		
Total investment						
x	+	1	y=	7000	-------------1	
Interest on both investments						
8.00%	x	+	7.00%	y=	500	
Multiply by		100				
8	x	+	7	y=	50000.00	--------2
Multiply (1) by			-8			
we get						
-8	x	-8	y=	-56000.00		
Add this to (2)						
0	x	-1	y=	-6000		
divide by		-1				
			y	=	6000	
Part I	8.00%	$	1000			
Part II	7.00%	$	6000	


		
						
CHECK
