Copper														
	percent	----------------			quantity									
Metal alloy I	50	----------------			x	Kg								
Pure copper	100	------	10	-	x	Kg								
Mixture	65	----------------	10											
	600													
50x+100	(10-x)	=65*10		
5000x+10000(10	-x)=65000				
5000x+	100000	-10000x	=	65000				
5000x	-	10000	x			=	65000	-	-100000				
-5000	x	=	-35000									
/	-5000													
	x			=	7		Kg			50.00%		Metal alloy I
