conversations.value: Can you explain how to solve this math problem: Together 3 friends watched 411 short videos. Kelsey watched 43 more than Ekon. Ekon watched 17 less than Uma. How many videos did Kelsey watch?
conversations.from: assistant
conversations.value: Let U = the number of videos Uma watched
  Ekon = U - 17
  Kelsey = (U - 17) + 43 = U + 26
  U + U - 17 + U + 26 = 411
  3U + 9 = 411
  3U = 402
  U = 134
  Kelsey = 134 + 26 = 160 videos
  Kelsey watched 160 videos.
