<human>:  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?
<bot>: Define a variable ** Let x represent the number of Pokemon Adelwolfe caught
How many Pokemon did Stan catch? ** Stan: 4x-13
How many Pokemon did Alex catch? ** Alex: 5+(4x-13)=4x-8
Write an equation ** Total: x+4x-13+4x-8=339
Combine like terms ** 9x-21=339
Add 21 to both sides ** 9x=360
Divide both sides by 9 ** x=<<40=40>>40 Pokemon
How many Pokemon has Stan caught? ** Stan:4(40)-13=147 Pokemon
