Answer 1

Ответ:

-у+0,5+2у=0,3

У=-0,2

Х= 0,2+0,5=0,7

Answer 2

It seems like you are trying to express a system of linear equations. However, the equations you provided seem to have some typographical errors. Let me clarify and correct these equations for you.

Assuming you intended to write the following system of linear equations:

1. $x + 2y = 0$
2. $3x = -y + 0.5$

If this is the system you are referring to, then we can solve it.

From equation (1), we can express $x$ in terms of $y$ as follows:

$x = -2y$

Now we substitute this expression for $x$ in equation (2):

$3(-2y) = -y + 0.5$

Simplify the equation:

$-6y = -y + 0.5$

Now solve for $y$:

$-6y + y = 0.5$

$-5y = 0.5$

$y = 0.5 / -5$

$y = -0.1$

Now that we have $y = -0.1$, we can find $x$ using the equation $x = -2y$:

$x = -2(-0.1)$

$x = 0.2$

So, the solution for the system of equations is $x = 0.2$ and $y = -0.1$.
