Resposta:

x+1      2

------ = -----

18         6

6. (x + 1) = 18 . 2

6x + 6 = 36

6x = 36 - 6

6x = 30

x = 30/6

x = 5

----------------------------------------------------------------------------------

35      21

---- = --------

x+8       3x

35 . 3x = 21 . (x+8)

105x = 21x + 168

105x - 21x = 168

84x = 168

x = 168/84

x = 2
