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
