Part I	4.00%		per annum	-------------	Amount invested =x	
Part II	6.00%		per annum	------------	Amount invested = y	
	1200					
Interest-----	62					
						
Part I	4.00%		per annum	---x		
Part II	6.00%		per annum	---y		
Total investment						
x	+	1	y=	1200	-------------1	
Interest on both investments						
4.00%	x	+	6.00%	y=	62	
Multiply by		100				
4	x	+	6	y=	6200.00	--------2
Multiply (1) by			-4			
we get						
-4	x	-4	y=	-4800.00		
Add this to (2)						
0	x	2	y=	1400		
divide by		2				
			y	=	700	
Part I	4.00%	$	500			
Part II	6.00%	$	700			
						
CHECK						
500	---------	4.00%	-------	20.00		
700	-------------	6.00%	-------	42.00		
Total			--------------------	62.00
