Question

PLEASE HELP DUE NOW!!! WILL MARK BRAINLIEST!!!

Answer 1

Answer:

(-5, -8)

Step-by-step explanation:

$- 9x + 5y = 5 \\ - 5x + 5y = - 15$

$- 9x + 5y = 5 \\ 5x - 5y = 15$

$- 4x = 20$

$- x = 5$

$x = - 5$

$-5( - 5) + 5y = - 15$

$25 + 5y = - 15$

$5y = -40$

$y = -8$

Answer 2

First, we merge the questions, to do that we simplify both of them to get a positive side.

To do that, we can first mutliply both sides of the second equation by -1.

Due to that, we get the equations

-9x+5y=5

5x-5y=15

If we add up the equations, we get -4x = 20

We can simplify and get x=-5

To get y, we can first input x into the second equation:

5(-5)-5y=15

-25-5y=15

Simplify and we get -8.

Therefore we have (-5,-8)
