Question 6
The usual thermometer has two scales, Celsius measured in $^\circ C$ and Fahrenheit measured in $^\circ F$ . If $m^\circ C$ is the same temperature as $n^\circ F$ , the conversion formula is $m\times\frac95+32=n$ . What is the value of m if $m^\circ C$ is the same temperature as $n^\circ F$ and $m+n=60$ ?
