We know that C/100=F-32/180 when C ranges from 0 to 100

                                                       C diff= 100    

                                                    F ranges from 32 to 212  

                                                      F diff =180

                  so, here A rabges from 14 to  133  A diff=119

                      and  F ranges from  36 to 87     B diff=51

                          Then equation becomes A-14/119=B-36/51

                        substitute A=B in the above equation we get

                                  A=B=52.5

                     This is my answer.

                      If we have better answer plz let me know

Hi there.. i have another answer for this...

9/5c=f-32 is the formula for converting celsius to fahrenheit..

when c=f is wht the question.. so place x in place of c and f

9x=5(x-32)

-4x=-32*5

x=-40.. hence the answer is -40
