Final Answer:
1) $ r = \dfrac{A}{2b + 6} $
2) $ x = \dfrac{F}{2wh + wL} $
3) $ b = \dfrac{w + u}{u + 9x} $
4) $ c = \dfrac{j(h - g)}{4g + jh} $
5) $ y = \dfrac{7x - 12}{x - 4} $
6) $ g = \dfrac{6h}{4(5 - h) + 12} = \dfrac{6h}{32 - 4h} $ (simplified: $ \dfrac{3h}{16 - 2h} $)
7) $ y = \dfrac{11x}{12} $
8) $ f = \dfrac{7w - 28m}{4} $
9) $ r = \dfrac{g(y - w)}{3 + w} $
10) $ p = \dfrac{3(g + f) + f}{g} = \dfrac{3g + 4f}{g} $
11) $ b = \dfrac{c - 2(a + b)}{1} $ → better: $ b = \dfrac{c - 2a - 2b}{1} $ — wait, solve properly:
From $ \dfrac{c}{a + b} - 2 = d $,
$ \dfrac{c}{a + b} = d + 2 $,
$ a + b = \dfrac{c}{d + 2} $,
so $ b = \dfrac{c}{d + 2} - a $
12) $ s = \dfrac{ge}{4e + 5} $
13) $ h = \dfrac{kq}{9 + 15q} $
14) $ e = \dfrac{ts}{100s + 9t} $
15) $ s = \dfrac{qy}{q + y} $
