setting x= very close to 0

So can you only set x to a very small number close to 0 when its something - x or can you also do this when it is something + x

I think you can do it when it is a quantity + x, but usually it is the products that have a quantity + x in an equilibrium equation, and you'll need to keep the x there so that you can solve for its value.
