Ответ:
1) y = 15/60
2) x = 33/70
3) x = 10/46
Пошаговое объяснение:
1) 34/60 + 8/60 + y = 41/60 + 16/60
42/60 + y = 57/60
y = 57/60 - 42/60
y = 15/60
Проверка:
34/60 + 8/60 + 15/60 = 41/60 + 16/60
42/60 + 15/60 = 41/60 + 16/60
57/60 = 57/60
2) 64/70 - (х + 26/70) = 5/70
64/70 - x - 26/70 = 5/70
64/70 - 26/70 = 5/70 + x
x + 5/70 = 38/70
x = 38/70 - 5/70
x = 33/70
64/70 - (33/70 + 26/70) = 5/70
64/70 - 59/70 = 5/70
5/70 = 5/70
3) x + 27/46 = 35/46 + 2/46
x + 27/46 = 37/46
x = 37/46 - 27/46
x = 10/46
10/46 + 27/46 = 35/46 + 2/46
37/46 = 37/46

Проверка:
34/60 + 8/60 + 15/60 = 41/60 + 16/60
42/60 + 15/60 = 41/60 + 16/60
57/60 = 57/60
2) 64/70 - (х + 26/70) = 5/70
64/70 - x - 26/70 = 5/70
64/70 - 26/70 = 5/70 + x
x + 5/70 = 38/70
x = 38/70 - 5/70
x = 33/70
Проверка:
64/70 - (33/70 + 26/70) = 5/70
64/70 - 59/70 = 5/70
5/70 = 5/70
3) x + 27/46 = 35/46 + 2/46
x + 27/46 = 37/46
x = 37/46 - 27/46
x = 10/46
Проверка:
10/46 + 27/46 = 35/46 + 2/46
37/46 = 37/46
