You don't have to eliminate units.
There are tricks to use them in solvers.
This is the best I could get.
Maybe a pro user can help you better.
roots() supports multiple argument btw.
Your equations has derivative.
Possibly reason of error by conventional solvers.
roots(), FindRoot(), solve() mostly doesn't like it.
