<PRE><B>Question 471414</B>
candy I = x lb
candy II= y lb
x+y=60

0.9x+1.5y=60*1.10

									
1	x	+	1	y	=	60	.............1		
0.9	x	+	1.5	y	=	66	.............2		
									
multiply (1)by 		-1.5							
Multiply (2) by		1							
-1.5	x		-1.5	y	=	-90			
0.9	x		1.5	y	=	66			
Add the two equations									
-0.6	x				=	-24			
/	-0.6								
x	=	40 lb  				
plug value of 			x	in (1)					
1	x	+	1	y	=	60			
40		+	1	y	=	60			
			1	y	=	60		-40	
			1	y	=	20			
				y	=	20 lb
