Ответ:
1. у = 15/60 или 1/4
2. х = 33/70
3. х = 10/46 или 5/23
Пошаговое объяснение:
1. 34/60 + 8/60 + у = 41/60 + 16/60
42/60 + у = 57/60
у = 57/60 - 42/60
у = 15/60 или 1/4
2. 64/70 - (х + 26/70) = 5/70
64/70 - х - 26/70 = 5/70
-х + 38/70 = 5/70
-х = 5/70 - 38/70
-х = -33/70
х = 33/70
3. х + 27/46 = 35/46 + 2/46
х + 27/46 = 37/46
х = 37/46 - 27/46
х = 10/46 или 5/23
