Question 1111969
Investment I	7.00%		per annum						
Investment II	10.00%		per annum						
									
x		+	y	10000	------------------------1				
7.00%	x	+	10.00%	y	=	760			
Multiply by		100							
7	x	+	10	y	=	76000		--------2	
									
Multiply (1) by			-7						
we get									
									
-7	x	-7	y	=		-70000.00			
									
Add this to (2)									
										+3	y	=		6000.00			
									
divide by		3							
									
			y	=		2000		investment at	10.00%
Balance						8000		investment at	7.00%
