Ah, it looks like, as with that issue, you can get solve to give you
an answer if you pass check=False:
In [21]: print(solve(-(S(21)/20)**(12*x) + 120, x, check=False))
[-log(120**(1/(-log(7355827511386641) +
Hello.
Why solve(-(21/20)**(12*x) + 120, x) gives empty set?

I guess it's just not implemented. I think the solution should be
log(120)/log(S(21)/20)/12. This is related to this issue

OK.
Thank you.
I just wondered because in sage it is not implemented as well.
