Symbolic Equation Problem

I have the following variables:
A=6.89272
B=1203.531
C=219.888
P=760
and the following expression:
TC=sym('log10(P)=A-(B/(C+T))')
T=solve(TC,'T')
T is the normal boiling point of benzene. I have to use MATLAB's symbolic capabilities to solve for T. However, no matter what method I try, I either get that T is undefined, or the symbolic expression of T. I cannot use eval(T).
Any suggestions?

A=6.89272
B=1203.531
C=219.888
P=760
syms T
TC = double(solve(log10(P)-A+(B/(C+T)),T));
Alternately, using your TC code,
solve(subs(TC),'T')
