Mr. Whine's Whine

Mr. and Mrs. Whine were carrying their packages home from the shopping mall when Mr. Whine started to complain that his load was too heavy.

Mrs. Whine turned to her husband and said, "I don't know why you're complaining because if you gave me one of your packages, I would have twice as many as you, and if I gave you just one of mine, we would have equal loads."

How many packages were each carrying?
