conversations.value: I need a clearer understanding of how to solve: Alex, Stan, and Adelwolfe are trying to catch them all, Pokemon that is.  Together they have caught 339 Pokemon.  Alex has caught 5 more than Stan, and Stan has caught 13 less than 4 times as many as Adelwolfe has caught. How many Pokemon has Stan caught?
conversations.from: assistant
conversations.value: Let x represent the number of Pokemon Adelwolfe caught
  Stan: 4x-13
  Alex: 5+(4x-13)=4x-8
  Total: x+4x-13+4x-8=339
  9x-21=339
  9x=360
  x=40 Pokemon
  Stan:4(40)-13=147 Pokemon
