If there are $o$ oranges and $b$ baskets then $2b + 4 = o$ and $(b-1)5 = o$; then $\boxed{b=3}$ and $\boxed{o=10}$.

Grade 5 arithmetic. From the second situation (the excess basket), move two oranges from one basket into the empty basket. Then take out the third orange from that basket, then three oranges from another basket - and get the excess four oranges. Thus three baskets, and ten oranges.
