Answer

\( x = -\frac{1}{5} \)

Solution

Решим уравнение: \[ 2 + 100x = -5x - 19 \] 1. Перенесём все члены уравнения с переменной \( x \) в одну сторону, а постоянные члены — в другую: \[ 100x + 5x = -19 - 2 \] 2. Сложим подобные члены: \[ 105x = -21 \] 3. Выразим \( x \): \[ x = \frac{-21}{105} \] 4. Сократим дробь: \[ x = \frac{-1}{5} \] Ответ: \[ x = -\frac{1}{5} \]

The Deep Dive

Для начала, давайте соберем все термы с \(x\) с одной стороны, а константы - с другой. Переносим \(-5x\) и \(-19\) на левую сторону уравнения: \(2 + 100x + 5x + 19 = 0\). Теперь это преобразуется в: \(105x + 21 = 0\). Теперь, вычтем 21 из обеих сторон: \(105x = -21\). Разделим обе стороны на 105: \(x = -\frac{21}{105} = -\frac{1}{5}\). Ответ: \(x = -\frac{1}{5}\).
