(x+8 17/36)+7 31/36=25 1/36
х = 25 1/36 - 7 31/36 - 8 17/36
х = 25 1/36 - (7 31/36 + 8 17/36)
х = 25 1/36 - 16 12/36
х = 8 25/36
ответ: 8 25/36
8 25/36
Пошаговое объяснение:
х + 8 17/36 + 7 31/36 = 25 1/36
х + (8 17/36 + 7 31/36) = 25 1/36
х + 15 48/36) = 25 1/36
х + 16 12/36 = 25 1/36
х = 25 1/36 - 16 12/36
х = 24 37/36 - 16 12/36
х = 8 25/36
