a] y x 1,7 = 85                                                                   b] 0,22 x y = 12,32

=> y = 85 /1,7                                                                 => y = 12,32 /0,22

= 50                                                                                     = 56

c] y x 0, 26 = 1,17 x 1, 04                                                   d] y x 1, 28 = 4,48 x 3 ,84

=> y x 0,26 = 1,2168                                                                     =>   y x 1,28 = 17,2032

=> y= 1,2168   / 0,26                                                                    => y= 17,2032/1,28

=4,68                                                                                            => y = 13,44
