Ответ:
Пошаговое объяснение:
1) X = 4 8/13 - 1 5/13 = 3 3/13
2) X = 3 9/14 - 1 3/14 = 2 6/14 = 2 3/7
3) X = 5 2/15 - 2 11/15 = 4 17/15 - 2 11/15 = 2 6/15 = 2 2/5
4) X = 4 13/16 + 2 5/16 = 6 18/16 = 7 2/16 = 7 1/8
в 5) и 6) не видно условие
5) x = 5 15/19 - 3 = 2 15/19
6) 3 - 1 11/18 = 2 18/18 - 1 11/18 = 1 7/18
