Question

980 - х + 930 - х = 890

Answer 1

980 - х + 930 - х = 890
1910-2х=890
2х=1910-890
2х=1020
х=1020:2
х=510

Проверим:
980-510+930-510=890
890=890

Answer 2

-x-x=890-980-930
-2x=-1020
x=-1020:(-2)
x=510

Answer 3

I can help you with your math problem. The equation you wrote is equivalent to:

$$980 - x + 930 - x = 890$$

To solve it, you need to simplify the left side by combining the terms with the same variable. Then you need to isolate the variable by moving the constant terms to the right side. Finally, you need to divide both sides by the coefficient of the variable. Here are the steps:

$$980 - x + 930 - x = 890$$ $$1910 - 2x = 890$$ $$-2x = 890 - 1910$$ $$-2x = -1020$$ $$x = -1020 \div (-2)$$ $$x = 510$$

The answer is $x = 510$. You can check this answer by plugging it into the original equation and verifying that both sides are equal. You can also find a similar explanation on this website.

Answer 4

Для решения этого уравнения, нужно вычесть 930 из 980.

980 - 930 = 50

Таким образом, результат уравнения 980 - х = 930 будет х = 50.

Подставляя значение х обратно в уравнение, получим: 980 - 50 = 930, что верно.
