а) (35 - x = 23rac{23}{27}) => (x = 35 - 23rac{23}{27} = 34rac{27}{27} - 23rac{23}{27} = 11rac{4}{27})
б) (47 - x = 21rac{14}{29}) => (x = 47 - 21rac{14}{29} = 46rac{29}{29} - 21rac{14}{29} = 25rac{15}{29})
в) (x - rac{32}{35} + rac{17}{35} = 2) => (x = 2 + rac{32}{35} - rac{17}{35} = 2 + rac{15}{35} = 2 + rac{3}{7} = 2rac{3}{7})
