товарищи, почему например, x +16 = 16 +16 =32 просто задачи по уравнение, и не могу понять, почему когда складываешь х +16 мы вместо х вставляем вновь 16? какие то может правила, напишите пожалуйста, буду благодарна.

Автор ответа: DeadWine

Пошаговое объяснение:

Смотри, выражения х+16 быть не может.

Вот к примеру выражение

х+16=32 может существовать

Как тут найти ответ

Так как тут сумма, то мы должны от суммы отнять известное число, получаем выражение

х=32-16

х=16

А к примеру если тут

х-16=32

нам нужно к полученному числу после равно прибавить известное

х=32+16

х=48

lusistola: благодарю
