Answer 1

Ответ:

Пошаговое объяснение:

197 - (x + 86) = 115

197 - x - 86 = 115

111 - x = 115

x = 111 - 115

x = -4

Answer 2

2 способ:

Решение:

197-(х+86)=115

х+86=197-115

х+86=82

х=82-86

х=-4

Проверка:

197-(-4+86)=115

197-82=115

115=115

Answer 3

To solve the equation 197 - (x + 86) = 115, we can follow these steps:

1. Distribute the negative sign to both terms inside the parentheses: 197 - x - 86 = 115

2. Combine like terms on the left side of the equation: (197 - 86) - x = 115 111 - x = 115

3. Move the constant term to the right side by subtracting 111 from both sides: 111 - x - 111 = 115 - 111 -x = 4

4. To solve for x, multiply both sides of the equation by -1 to isolate x: (-1)(-x) = (-1)(4) x = -4

Therefore, the solution to the equation is x = -4.
