Sequences and Limit Superior

Suppose that xn x and the sequence (yn) is bounded. Show that

___ ___
lim (xn + yn) = lim xn + lim (yn).

___
I know that since (xn) converges lim xn = lim (xn) and that

___ __ ___
lim (xn + yn) </= lim xn + lim yn.

Thus the equality in this equation must come from the fact that (yn) is bounded, but I am not sure how to get there. Please help.
