Question 831288
Part I	7.00%		per annum	-------------	Amount invested =x	
Part II	8.00%		per annum	------------	Amount invested = y	
	7000					
Interest-----	537.00					
						
Part I	7.00%		per annum	---x		
Part II	8.00%		per annum	---y		
Total investment						
x	+	1	y=	7000	-------------1	
Interest on both investments						
7.00%	x	+	8.00%	y=	537	
Multiply by		100				
7	x	+	8	y=	53700.00	--------2
Multiply (1) by			-7			
we get						
-7	x	-7	y=	-49000.00		
Add this to (2)						
0	x	1	y=	4700		
divide by		1				
			y	=	4700	
Part I	7.00%	$	2300			
Part II	8.00%	$	4700			
						
CHECK						
2300	---------	7.00%	-------	161.00		
4700	-------------	8.00%	-------	376.00
