Question

Сумма трёх чисел равна 18 Сумма 1 и 3 числа равна 10 Сумма 2 3 числа равна 8 Найдите эти числа

Answer 1

 1=10; 2=8; 3=0 по-другому просто не получается.

Answer 2

I can understand and communicate in Russian. Your question is about finding three numbers that satisfy some conditions. Here is a detailed answer:

Let the three numbers be $x$, $y$, and $z$. Then, we have the following equations:

$$ x + y + z = 18 \\ x + z = 10 \\ y + z = 8 $$

To solve this system of equations, we can use the method of elimination. First, we subtract the second equation from the first one to get:

$$ x + y = 8 $$

Then, we subtract the third equation from the first one to get:

$$ x - y = 10 $$

Now, we can add these two equations to eliminate $y$ and find $x$:

$$ 2x = 18 \\ x = 9 $$

To find $y$, we can substitute $x = 9$ into either of the equations involving $y$. For example, using the first equation, we get:

$$ 9 + y = 8 \\ y = -1 $$

Finally, to find $z$, we can substitute $x = 9$ and $y = -1$ into any of the original equations. For example, using the second equation, we get:

$$ 9 + z = 10 \\ z = 1 $$

Therefore, the three numbers are $x = 9$, $y = -1$, and $z = 1$. You can check that they satisfy all the given conditions.

I hope this answer was helpful. If you have any other questions, feel free to ask me.
