The value you seek has 4 subtracted, the log taken, and the result multiplied by 3. To find that value, divide by 3, take the anti-log, then add 4. (Undo the steps that were done to the variable.)
  3Ln[x-4] = 6
  Ln[x-4] = 2    (divide by 3)
  x - 4 = e^2    (take the anti-log)
  x = 4 + e^2    (add 4)
  x ≈ 11.389    (compute the result)
