100001 - (х + 44864) = 31587
100001 - х - 44 864 = 31587
100001 - 44 864 - 31587 = х
х = 23550
Проверка:
100001 - (23550 + 44864) = 100001 - 68414 = 31587
31587 = 31587
100001 - (х + 44864) = 31587
100001 - х - 44 864 = 31587
100001 - 44 864 - 31587 = х
х = 23550
Проверка:
100001 - (23550 + 44864) = 100001 - 68414 = 31587
