Answer 1

64 - 8 - 4

Explanation:

If the temperature at the *end* of the day is 64. That means the 8 and the 4 were already added to the 64, so if you want to know what it was before they were added you just subtract 8 and 4 from 64.

Answer 2

The expression that shows the temperature at the start of the day is 64 - 8 - 4
