conversations.value: Eliza has 4 siblings. The total height of all 5 siblings combined is 330 inches. Two of her siblings are both 66 inches tall. Another sibling is 60 inches tall. If Eliza is 2 inches shorter than the last sibling, how tall is Eliza?
  Work out the solution step by step.
conversations.from: assistant
conversations.value: The first three siblings are 66 +66 + 60 = 192 inches tall.
  Since the total of all the siblings is 330 inches, Eliza and the last sibling are 330 - 192 = 138 inches tall combined.
  If Eliza's height = h, 138 inches = h + (h+2).
  (138-2)/2 = 68 inches.
  Eliza is 68 inches tall.
