The temperature at the beginning of the day was 6.2°F

Let x represent the temperature at the beginning of the day.

Since, the temperature of a city doubles during the day, and then decreases by 14.1ºF after the sun goes down, hence:

Temperature at end of day = 2x - 14.1

Also, the temperature at the end of the day is −1.7°F, hence:

2x - 14.1 = -1.7

2x = 12.4

x = 6.2°F

The temperature at the beginning of the day was 6.2°F
