Try starting off by putting weights on the $1$ hook. How many will you need to balance with $10$?

What about trying the $2$ hook? How many will you need this
time?

Can you keep going in this way?

If I had two weights on the $10$ hook, what would this be the
same as in total?

If I then hang two weights on the other side, what would that balance with? So how many will I need on the $2$ hook to balance with the two on the $10$?
