A balanced lever has two weights on it, the first with mass #9 kg # and the second with mass #32 kg#. If the first weight is # 6 m# from the fulcrum, how far is the second weight from the fulcrum?

Torque can be defined as
or for the given data:
Second weight is
Let the the second weight be
As the lever is balanced, moment (
