Answer 3

Solve for C
\[\Large F = \frac{9}{5}C+32\]
\[\Large F-32 = \frac{9}{5}C+32-32\]
\[\Large F-32 = \frac{9}{5}C\]
\[\Large \frac{9}{5}C = F-32\]
\[\Large \frac{5}{9}*\frac{9}{5}C = \frac{5}{9}*\left(F-32\right)\]
\[\Large C = \frac{5}{9}*\left(F-32\right)\]
\[\Large C(F) = \frac{5}{9}*\left(F-32\right)\]
So you are correct
