Lets try and substitute F=75 in our equation.
F=9/5C+32
75 = 9/5C+32
Lets put the variables on one side and the numbers on the other side. Every variable or number that will change sides, will have their sign changed from a + into a - and vice versa.
9c/5 = 75-32
9c/5 = 43
Lets try and multiply both sides with 5.
(9c x 5) / 5 = 43 x 5
9c = 215
Divide both sides with 9.
9c/9 = 215 / 9
c = 23.88
