At what temperature (degrees Celsius) is the Fahrenheit scale reading equal to (a) 4 times that of the Celsius and (b) 1/5 times that of the Celsius?
If anybody could explain to me how to get the answer along with the answers I'd greatly appreciate it.
Thank you.

we start with the relationship between degrees F and degrees C:
F = 1.8C+32 where F is the degrees in Fahrenheit and C is the degrees in C
we are first asked to find when F = 4C
set F = 4C in the equation above and get
4C = 1.8C +32
2.2C = 32
C = 14.54 deg C and accordingly the temp in F is 58.18 deg F
b) now, F = 1/5 C = 0.2C
following the same procedure
0.2C = 1.8C +32
-1.6C = 32
C = - 20 deg C the corresponding temp in deg F is - 4 F, and the relationship of F=C/5 holds
