Question 746292
Part I	9.00%		per annum	-------------	Amount invested =x		
Part II	11.00%		per annum	------------	Amount invested = y		
	7000						
Interest-----	700.00						
							
Part I	9.00%		per annum	---x			
Part II	11.00%		per annum	---y			
Total investment							
x	+	1	y=	7000	-------------1		
Interest on both investments							
9.00%	x	+	11.00%	y=	700		
Multiply by		100					
9	x	+	11	y=	70000.00	--------2	
Multiply (1) by			-9				
we get							
-9	x	-9	y=	-63000.00			
Add this to (2)							
0	x	2	y=	7000			
divide by		2					
			y	=	3500		
Part I	9.00%	$	3500				
Part II	11.00%	$	3500				
							
CHECK							
3500	---------	9.00%	-------	315.00			
3500	-------------	11.00%	-------	385.00
