Question

9(x-1)=x+15 Найдите корень уравнения

Answer 1

9 (х-1)=х+15
9х-9=х+15
9х-х=15+9
8х=24
Х=3
Ответ:3

Answer 2

9x-9=x+15
9x-x=15+9
8x=24
x=24:8
x=3

Answer 3

Давайте решим уравнение 9(x-1) = x+15 и найдем его корень.

1. Раскроем скобки в уравнении: 9x - 9 = x + 15.

2. Сгруппируем переменные справа и числа слева: 9x - x = 15 + 9.

3. Упростим выражение: 8x = 24.

4. Разделим обе части уравнения на 8, чтобы изолировать переменную x: x = 24 / 8.

5. Выполним деление: x = 3.

Таким образом, корнем уравнения 9(x-1) = x+15 является x = 3.

Answer 4

I can help you solve this equation. Here are the steps:

- First, we need to expand the parentheses by multiplying 9 by x and -1. This gives us 9x - 9 = x + 15. - Next, we need to collect the x terms on one side and the constant terms on the other. To do this, we subtract x from both sides and add 9 to both sides. This gives us 8x = 24. - Finally, we need to isolate x by dividing both sides by 8. This gives us x = 3.

Therefore, the root of the equation is 3. You can check this by plugging it back into the original equation and verifying that both sides are equal.

You can also use online calculators to solve equations, such as [this one](https://ru.symbolab.com/solver/equation-calculator). However, it is important to understand the steps and the logic behind them. I hope this was helpful.
