Temperature can be measured in both Celcius scale (°C) and Fahrenheit scale (°F). The relation between both the scales is given by F=15(9C+160).
If the freezing point of a liquid is −60°C, using the relation given above, find the freezing point of the same liquid in °F.

Step-by-step explanation:
By conversion of temperature formula We know that,
℉=(℃×9/5)+32(i)
℃=(℉−32)×5/9(ii)
Let x be the reading where both C and F scale gives same value:
x=5/9×(x−32)
x=(5/9)x−17.778
x−(5/9)x=−17.778
0.44x=−17.778
x=−40℃or℉
