Let x be the temperature at midnight.
From midnight to 6:00 a.m., the temperature rose 8°C, so at 6:00 a.m., the temperature was x + 8.
We are also given that at 6:00 a.m., the temperature was negative 20°C, so we can write:
x + 8 = -20
Subtracting 8 from both sides, we get:
x = -28
Therefore, the temperature at midnight was -28°C.
