a solution is to be kept between 86 degree and 95 degree fahrenheit what is the range of temperature in degree Celsius if the Celsius / fahrenheit conversion formula is given by F = 9 /5 C + 32

good evening__________✌️✌️✌️

Given F = C*9/5 + 32

=> F-32 = C*9/5

=> C = {5*(F-32)}/9 .............1 

Now PUT F = 86 in equation 1, we get

      C = {5*(86-32)}/9  

=> C =  (5*54)/9

=> C = 5*6

=> C = 30

Again put F = 95 in equation 1, we get

      C = {5*(95-32)}/9  

=> C =  (5*63)/9

=> C = 5*7

=> C = 35

So range of solution is kept it between 30° C and 35° C
