Пошаговое объяснение:

34/60 + 8/60 + у = 41/60 + 16/60

42/60 + у = 57/60

у = 57/60 - 42/60

у = 15/60

у = 1/4

64/70 - (х + 26/70) = 5/70

х + 26/70 = 64/70 - 5/70

х + 26/70 = 59/70

х = 59/70 - 26/70

х = 33/70

х + 27/46 = 35/46 + 2/46

х + 27/46 = 37/46

х = 37/46 - 27/46

х = 10/46

х = 5/23
