conversations.value: Marilyn's first record sold 10 times as many copies as Harald's. If they sold 88,000 copies combined, how many copies did Harald sell?
  Give me a detailed solution.

conversations.value: Let m be the number of copies Marilyn sold and h be the number Harald sold. We know that m + h = 80,000 and m = 10h.
  Substituting the second equation into the first, we get 10h + h = 88,000
  Combining like terms, we get 11h = 88,000
  Dividing both sides by 11, we get h = 8,000
