Part I	8.00%		per annum	-------------	Amount invested =x		
Part II	12.00%		per annum	------------	Amount invested = y		
	13000						
Interest-----	1240.00						
							
Part I	8.00%		per annum	---x			
Part II	12.00%		per annum	---y			
Total investment							
x	+	1	y=	13000	-------------1		
Interest on both investments							
8.00%	x	+	12.00%	y=	1240		
Multiply by		100					
8	x	+	12	y=	124000.00	--------2	
Multiply (1) by			-8				
we get							
-8	x	-8	y=	-104000.00			
Add this to (2)							
0	x	4	y=	20000			
divide by		4					
			y	=	5000		
Part I	8.00%	$	8000				
Part II	12.00%	$	5000				
							
CHECK							
8000	---------	8.00%	-------	640.00
