Question

5 2/13-(ікс-5/13)=1 4/13

Answer 1

Ответ:

х = 4 3/13

Пошаговое объяснение:

5 2/13 - (х - 5/13) = 1 4/13

х = 5 2/13 + 5/13 - 1 4/13

х = 5 7/13 - 1 4/13

х = 4 3/13

-------

5 2/13 - (4 3/13 - 5/13) = 1 4/13

5 2/13 - (3 16/13 - 5/13) = 1 4/13

5 2/13 - 3 11/13 = 1 4/13

4 15/13 - 3 11/13 = 1 4/13

1 4/13 = 1 4/13 - верно
