conversations.value: Can you explain how to solve this math problem: Jenny is older than Charlie by five years, while Charlie is older than Bobby by three years. How old will Charlie be when Jenny becomes twice as old as Bobby?
conversations.from: assistant
conversations.value: Jenny is older than Charlie by 5 years who is older than Bobby by 3 years, so Jenny is older than Bobby by 5+3 = 8 years
  Jenny will be twice as old as Bobby when he is 8*2 = 16 years old
  Jenny is 5 years older than Charlie so when Jenny is 16, Charlie will be 16-5 = 11 years old
