conversations.value: I need help with this problem:
  Becca, Smendrick, and PJ have collections of Magic Cards.  There is a total of 341 cards.  Becca has 12 more than Smendrick, and Smendrick has 3 times the amount of cards that PJ has.  How many cards does Becca have?
conversations.from: assistant
conversations.value: Let x represent the number of cards PJ has
  Smendrick:3x
  Becca:3x+12
  Total:x+3x+3x+12=341
  7x+12=341
  7x=329
  x=47 cards
  Becca:3(47)+12=153 cards
