I hang three weights on the 8 hook on the left-hand side of the equaliser.

If I have a maximum of four weights left, where could I hang them on the right-hand side of the equaliser so that it balances?

Are there any other ways of doing it? (I don't need to use all four weights.)

Now I hang three weights on the 10 hook and one on the 6 hook on one side of the equaliser.

If I have six weights, where could I hang them on the other side to make it balance?
