HELP 30 POINTS!!!!!!!!!!!!!!!!!!!!!


Please explain this!!!

Answer 1

[2, -4]

Explanation:

{y + x = -2

{5x - 3y = 22

-⅕[5x - 3y = 22]

{y + x = -2

{-x + ⅗y = -4⅖

_______________

1⅗y = -6⅖

____ ____

1⅗ 1⅗

y = -4 [Plug this back into both equations above to get the x-coordinate of 2]; 2 = x

I am joyous to assist you anytime.

Answer 2

First, multiply the first equation by 3 to get:

`3x+3y=-6`

Then, add the two equations together to get

`8x=16`

We can follow that x=2. Plugging in x=2, we get that y=-4.

Therefore, the solution of (2,-4)
