Econ help - Finding the market Equilibrium

Qd = -lnP+ln15
Qs = ln(P-2)
I know that to find the market EQ is to do Qd = Qs, but I can see there are some logarithmic equations and I'm pretty terrible at it rn. Is it simply expanding the bracket, trying to isolate P to find the value of it or am I missing something?

Assuming it is Qs = Qd (no knowledge of that step), you want to take inverse logs (exponentiation) of both sides involving P. However, its easier(?) to write
-ln(P)+ln(15)
as a single log function first using the usual rules to get something like
ln(#)

So have a go at that.
