question 1) $\displaystyle F = \frac{9}{5}C + 32$ solve for "C"

answer is $\displaystyle C = \frac{5}{9}(F - 32)$

How does the fraction end up inverted? I get it to $\displaystyle F - 32 = \frac{9}{5}C$ then I don't know what to do

question 2) $\displaystyle d = v.t + \frac{1}{2}at^2$ solve for "a"

answer is $\displaystyle a = \frac{2 (d-v.t)}{t^2}$

help is very much appreciated and somewhat urgent!
