    First, I'm just going to talk about 1 of them say 23^0 F
    You will have to rearrange the equation either before or after you substitute in 23 for F (to make C the subject)

    Since you have 2 temperatures to change from Farenheit to Celsius it makes more sense to rearrange the equation to make C the subject first.

    F = 9/5 C +32
    times both sides by 5 (to get rid of the fraction)
    ...
    5F = 9C+160
    Can you do it from here?

    Once you make C the subject you can substitute in the 2 values of F (one at a time ) and get the answer that you seek easily.
