conversations.value: Last year Dallas was 3 times the age of his sister Darcy. Darcy is twice as old as Dexter who is 8 right now. How old is Dallas now?
  Give me a solution to this problem
conversations.from: assistant
conversations.value: Darcy = 2*Dexter = 2*8 = 16
  Last year Darcy was 16 - 1 = 15
  Dallas was 3 times Darcy last year = 3*15 = 45
  Dallas is a year older now = 45 + 1 = 46
  Dallas is 46 years old now.
