Пришла к ответу 15x/16+15/16,что делать дальше? :P

Skazhem, vsja posilka x.

TOGDA:

Gene x-x/2-1/2 = (x-1)/2 ( ostatok)
Shapokljak ostatok - ostatok/2 - 1/2 = (x-1)/2 - (x-1)/4 - 1/2 = (x-3)/4 (novii ostatok)
Lariske ostatok -ostatok/2-1/2 =(x-3)/4 -(x-3)/8-1/2 =(x-7)/8 (novii ostatok)
Gale ostatok - ostatok/2-1/2=0 (karsina pusta)
(x-7)/8 - (x-7)/16-1/2 = 0
(x-15)/16=0
x=15
