The equation shown presented how to convert degrees Celcius to degrees Fahrenheit. In order to get and solve for F given the equation, these are the steps.
C = [5 * (F-32)] / 9
9C = 5 * (F - 32)
9C = 5F - 160
9C + 160 = 5F
5F = 9C + 160
F = (9C / 5) + (160 / 5)
F = [ (9/5) * C ] + 32
So, the correct answer for this question is F = [ (9/5) * C ] + 32
