Question

(21-X) *12=96 Уравнение

Answer 1

(21-х)*12=96
252-12х=96
-12х=96-252
-12х=-156 |: (-12)
х=13

Answer 2

Ответ: х=13

(21-х)*12=96

Раскроем скобки:

21*12-(-х)*12=96

Посчитаем:

252-12х=96

Перенесем число в правую часть уравнения (поменяв знак), а переменную оставим в левой:

-12х=96-252

-12х=-156

х=-156:-12

х=13

Проверяем:

(21-13)*12=96

96=96

Все правильно!

Answer 3

To solve the equation "(21 - X) * 12 = 96," we can follow these steps:

1. Distribute the 12 on the left side of the equation: 12 * 21 - 12 * X = 96

2. Simplify the equation: 252 - 12X = 96

3. Move the constant term to the right side of the equation by subtracting 252 from both sides: -12X = 96 - 252 -12X = -156

4. Divide both sides of the equation by -12 to solve for X: X = (-156) / (-12) X = 13

Therefore, the solution to the equation is X = 13.
