Ответ:

Неравенство |x| < -8 не имеет решений.

Пошаговое объяснение:

Найти целые значения, при которых неравенство верно:
|x| < -8.

Модуль числа a равен самому этому числу  a, если a ≥ 0; и равен противоположному числу, если a < 0.

Модуль числа величина неотрицательная:
|x| ≥ 0 при любом значении x.

В нашем неравенстве требуется найти все целые значения переменной x, модуль которых меньше -8, то есть меньше отрицательно числа.

Так  как модуль числа величина неотрицательная, то таких значений переменной x не существует.
Решением неравенства является пустое множество ∅.

Неравенство не имеет решений.
