###### Exercise2

To convert a temperature measured in degrees Fahrenheit to degrees Celsius, there is a formula:

$$\displaystyle{ C={\frac{5}{9}\!\left(F-32\right)} }$$

where $$C$$ represents the temperature in degrees Celsius and $$F$$ represents the temperature in degrees Fahrenheit.

If a temperature is $$122 {^\circ}\text{F}\text{,}$$ what is that temperature measured in Celsius?
