To combine the expressions (x+2)/x and -(y-2)/y, we need to find a common denominator. The common denominator is xy. Multiplying the first fraction by y/y and the second fraction by x/x, we get (xy+2y)/xy - (x-y+2x)/xy. Simplifying further, we have (xy+2y - x+y-2x)/xy, which can be rearranged as (xy - x + y + 2y - 2x)/xy. Combining like terms, we get (xy - 2x + 3y)/xy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
