найти корень уравнения с проверкой 3 5/16+(d-1 7/16)=9 1/16

3 5/16+(d-1 7/16)=9 1/16,3 5/16 + d - 1 7/16 = 9 1/16,d = 9 1/16 - 3 5/16 + 1 7/16,d = (9 - 3 + 1) + (1/16 - 5/16 + 7/16),d = 7 + 3/16.d = 7 3/16,проверка:3 5/16 + (7 3/16 - 1 7/16) = 9 1/16,3 5/16 + 5 12/16 = 9 1/16,8 + 17/16 = 9 1/16,8 + 1 1/16 = 9 1/16,9 1/16 = 9 1/16
