°
C. What was the temperature at midnight?
.
Let x be the temperature at midnight.
From midnight to 6:00 am, the temperature rose 8°C. So at 6:00 am, the temperature was x + 8°C.
At 6:00 am, the temperature was −20°C.
We can write an equation:
x + 8 = −20
To solve for x, we need to isolate it on one side of the equation.
x + 8 - 8 = -20 - 8
x = -28
Therefore, the temperature at midnight was -28°C.
