Answer 2

you can do this by solving the equations by the elimination method.
Can you do that?

Answer 3

Uhhhhhhhhhhhhh IDK

Answer 4

Well you could also plug the given values of x and y into the 2 equations and see which one fits

Answer 5

Note the ordered pair (-3,-2) means that x = -3 when y = -2.
Plug these into the 2 equations and see if they fit.

Answer 6

So take
2x + y = -8:- x = -3 and y = -2

2(-3) + -2 = -6 - 2 = -8 Thats fits fine.
Now try the second equation x - y = -4

-3 - -2 = -3+2 = -1 That does NOT fit so the answer is not (-3, -2)
