conversations.value: In 7 years, Kaylee will be 3 times as old as Matt is now. If Matt is currently 5 years old, how old is Kaylee now?
  Can you solve this problem?

conversations.value: In 7 years, Kaylee will be 5 * 3 = 15 years old
  Let x be the age Kaylee is now.
  After 7 years, Kaylle will be 15 years old, so x + 7 = 15
  x = 15 - 7
  x = 8 years old
