You need some sort of formula for this question. But you more or less have to invent it.
Formula
Temperature midnight = noon - temperature drop
Givens
temperature drop = 28.4
temperature midnight = -1.9
Temperature noon = x
Solution
-1.9 = x - 28.4 Add 28.4 to both sides
-1.9 + 28.4 = x-28.4+28.4 Combine
Answer
26.5 = x
