Terri	8.00%per annum	-------------	Amount invested =x	
Juan	7.00%per annum	------------	Amount invested = y	
	15000					
Interest-----	1150					
Sum of investments						
x	+	y=	15000	-------------1	
Interest earned on both investments						
8.00%	x	+	7.00%	y=	1150	
Multiply by		100				
8	x	+	7	y=	115000.00	--------2
Multiply (1) by			-8			
we get						
-8	x	-8	y=	-120000.00		
Add this to (2)						
0	x	-1	y=	-5000		
divide by		-1				
			y	=	5000	
Terri	7.00%	$	5000			
Juan	8.00%	$	10000
