Question 475553
Investment I	8.00%		per annum						
Investment II	5.00%		per annum						
									
x+y	7000	------------------------1				
8.00%x+5.00%y=$476.00			
Multiply by 		100							
8x+5y=	$47,600.00		--------2	
									
Multiply (1) by	-8						
we get									
									
-8x-8y=	-56000.00			
								
Add this to (2)									
									
-3y=-$8,400.00			
									
divide by-3							
									
y=$2,800.00----investment at 	5.00%
Balance	$4,200.00----investment at 	8.00%
