The question is not phrased appropriately enough to derive meaning from it. Taken literally, you wish the number 87 to have a number subtracted from it. And that number is to be three times a number that is greater than 165. 166 is greater. And three times that is 498. And 87 minus 498 is negative 411. However, there an infinite number of numbers that are greater than 165. That was the first.
