Part I	4.00%		per annum	-------------	Amount invested =x	
Part II	10.00%		per annum	------------	Amount invested = y	
	70000					
Interest-----	4000.00					
						
Part I	4.00%		per annum	---x		
Part II	10.00%		per annum	---y		
Total investment						
x	+	1	y=	70000	-------------1	
Interest on both investments						
4.00%	x	+	10.00%	y=	4000	
Multiply by		100				
4	x	+	10	y=	400000.00	--------2
Multiply (1) by			-4			
we get						
-4	x	-4	y=	-280000.00		
Add this to (2)						
0	x	6	y=	120000		
divide by		6				
			y	=	20000	
Part I	4.00%	$	50000			
Part II	10.00%	$	20000			
						
CHECK						
50000	---------	4.00%	-------	2000.00		
20000	-------------	10.00%	-------	2000.00		
Total			--------------------	4000.00
