conversations.value: Can you guide me through solving this problem: Lindsay has 4 dolls with blonde hair; four times more dolls with brown than blonde hair; 2 fewer dolls with black than brown hair. How many more dolls with black and brown hair combined does Lindsay have than blonde-haired dolls?
conversations.from: assistant
conversations.value: Lindsay has 4 x 4 = 16 brown-haired dolls.
  She has 16 - 2 = 14 black-haired dolls.
  Thus, Lindsay has 16 + 14 = 30 black and brown hair dolls combined.
  Therefore, she has 30 - 4 = 26 more dolls with black and brown hair combined than blonde-haired dolls.
