    #8. x - he had caught, additionally he has cached 3x, totally he has x+3x = 24, x = 6!

      no that is wrong. lets say the number of fish he caught was x. If he had 3 times more fish than he caught which is 3x, that would be 24 more than the amount of fish he caught, so that would be x+24.
      3x=x+24
      3x-x=x+24-x
      2x=24
      x=12
