Question

Y - x = - 2 y + x = 0

Answer 1

y=x-2

y=-x

-x=x-2

-2x=-2

x=1

y=-1

Answer 2

Ответ:{1;-1}

$\left \{ {{y-x=-2} \atop {y+x=0}} \right. \\2y=-2\\y=-1$

Если у= -1,то х=0-у

                     х=1

Answer 3

It looks like you've provided a system of two linear equations with two variables, $x$ and $y$. The equations are:

1. $Y - x = -2$
2. $y + x = 0$

It seems like you might want to solve for the values of $x$ and $y$ that satisfy both equations. Let's solve this system of equations:

First, let's solve the second equation for $y$: $y = -x$

Now substitute the value of $y$ from the second equation into the first equation: $Y - x = -2$ $-x - x = -2$ $-2x = -2$ $x = 1$

Now that we have the value of $x$, we can substitute it back into the second equation to find $y$: $y = -x = -1$

So, the solution to the system of equations is $x = 1$ and $y = -1$. This is the point where both equations intersect and are satisfied simultaneously.
