At what tempreature farenhite scale and celcius scale show the same reading

-40°F = -40°C

Explanation:

To convert Celsius to Fahrenheit, the following equation is used:

F = 1.8C + 32

When the temperature on the Fahrenheit scale is the same on the Celsius scale, that means F = C.  Substituting:

C = 1.8C + 32

0 = 0.8C + 32

-0.8C = 32

C = -40

Therefore -40°F = -40°C.
