5+ln(8x)=23-2ln(x)
ln(8x)=18-2ln(x)
ln(8x)+2ln(x) = 18
ln(8x)+ln(x^2) = 18
ln(8x)(x^2) = 18
ln(8x^3) = 18
8x^3 = e^18
x^3 = (e^18)/8
x = cube_root((e^18)/8)
x = 201.7144

5+ln(8x)=23-2ln(x)
5ln(e)+ln(8x)=23ln(e)-ln(x^2)
ln(e^5*8x)=ln(e^23/x^2)
e^5*8x=e^23/x^2
e^5*8x^3=e^23
8x^3=e^23/e^5
8x^3=e^18
(2x)^3=e^18
2x=e^6
x=(e^6)/2
Answer is x=(e^6)/2
