conversations.value: This math problem has got me stumped: In 5 years, Raven will be 4 times as old as Phoebe. If Phoebe is currently 10 years old, how old is Raven?
  Can you show me the way?

conversations.value: In five years, Phoebe will be 10+5 = 15 years old.
  If Raven is four times as old as Phoebe in fifteen years, he will be 4*15 = 60 years old in 5 years.
  Currently, Raven is 60-5 = 55 years old.
