Does it, really?
In[98]:= NSolve[3*x+(1/(x-5))==15+(1/(x-5)),x]
Out[98]= {{x->5.}}
In[99]:= 3*x+(1/(x-5))==15+(1/(x-5))/.{x->5.`}
During evaluation of In[99]:= Power::infy: Infinite expression 1/0. encountered. >>
During evaluation of In[99]:= Power::infy: Infinite expression 1/0. encountered. >>
Out[99]= ComplexInfinity==ComplexInfinity
