From midnight to 6:00 am, the temperature rose 8°C. At 6:00 am, the temperature was -20°C. What was the temperature at midnight?
Let x be the temperature at midnight in degrees Celsius.
From midnight to 6:00 am, the temperature rose 8°C, so at 6:00 am it was x + 8°C.
Since at 6:00 am the temperature was -20°C, we can write:
x + 8 = -20
Subtracting 8 from both sides:
x = -28
Therefore, the temperature at midnight was -28°C.
