Can anyone tell me what's wrong with this algebraic proof?
This is a simple algebra proof showing that 2 equals one:
Defintion: X=Y
Multiply each side by x: 2x=xy
Subtract 2y from each side: 2x-2y=xy-2y
Factor: (x+y)(x-y)=y(x-y)
Divide by (x-y): x+y=y
Replace x with y per definition: 2y=y
Divide by y: 2=1
Can you figure out the flaw in the prrof.

I would think that it would be under games and recreation. I do not consider the subcategories such as camping and climbing as sporting events.

My wife and I are planning a trip to Vegas this summer and are looking for some sightseeing tours and are not planning to rent a car as we are staying on the Strip.
Specifically, are they a good deal? Or, would it be better to rent a car for a day? (We will be there for three days)
