Question

7x -1 - 2x + 3 = 3x-5y 4 3 2 5x-3y + x+5y = 3x - y 3 2

Answer 1

1)5х+2=3х-5у

5х-3х+5у=-2

2х+5=-2

2)6x+2y=3x-y

6x+2y-3x-y

6x+2y-3x+y=0

3x+3y=0

x+y=0

Answer 2

It seems like you've provided two equations, but the formatting is a bit unclear. Let me interpret the equations as follows:

$7x - 1 - 2x + 3 = 3x - 5y$

$5x - 3y + x + 5y = 3x - y$

Now, let's simplify and solve this system of equations step by step.

For the first equation:

$(7x - 2x) + (-1 + 3) = 3x - 5y$

$5x + 2 = 3x - 5y$

$2x = -5y - 2$

For the second equation:

$(5x + x) + (-3y + 5y) = 3x - y$

$6x + 2y = 3x - y$

$6x + 2y + y = 3x$

$6x + 3y = 3x$

$3y = -3x$

$y = -x$

Now you have two equations:

$2x = -5y - 2$

$y = -x$

You can substitute the second equation into the first one to solve for $x$:

$2x = -5(-x) - 2$

$2x = 5x - 2$

$-3x = -2$

$x = \frac{2}{3}$

Now that you know the value of $x$, you can find the value of $y$ using the second equation:

$y = -\frac{2}{3}$

So, the solution to the system of equations is $x = \frac{2}{3}$ and $y = -\frac{2}{3}$.
