Use properties of logartithms to simplify and solve. Thanks.

ln(x-3)-ln(11x-23)+in(x-1)=0

I believe it may be x=2,x=13
Did you test your answers?
Obviously x= 2 cannot be right since it would make
the second term undefined,
ln(22-23) = ln(-1), which is undefined

using the rules of logs, we get
ln[(x-3)(x-1)/(11x - 23) ] = 0
(x-3)(x-1)/(11x - 23) = e^0 = 1
x^2 - 4x + 3 = 11x - 23
x^2 - 15x+ 26 = 0
(x-2)(x-13) = 0
so x=2 or x=13

check for x=13
LS = ln10 - ln120 + ln12
= ln(10(12)/120) = ln 1 = 0 = RS

x = 13
