-----------
IF it's
(4x+5)*log(3) = log(1/2)
4x+5 = log(1/2)/log(3)
4x = log(1/2)/log(3) - 5
x = (log(1/2)/log(3) - 5)/4

^{(4x\,+\,5)}\ -\ 2\ =\ -1)
^{(4x\,+\,5)}\ = 1)
}\ =\ \frac{1}{2})
}\)\ =\ \ln\(\frac{1}{2}\)\ =\ -\ln(2))
\ln(3)\ =\ -\ln(2))
}{\ln(3)})
}{\ln(3)}\ -\ 5)
}{\ln(3)}\,-\,5}{4})
The rest is just arithmetic.
