conversations.value: Today is my birthday and I'm three times older than I was six years ago. What is my age?
  How to solve this?
conversations.from: assistant
conversations.value: We know that my age divided by three is equal to my age minus six therefore X/3 = X-6 where X = My age
  This means that X = 3X - 18 because we can multiply both sides by 3
  This also means that -2X=-18 because we can subtract 3X from the right side.
  Therefore X = 9 because - 18/-2 = 9
