Answer:

x = 1 and y = -28

(1,-28)

:- Solution

Elimination & Substitution method

8x + 4y = -104 →multiply by 1

4x + y = - 24 →multiply by 4

8x + 4y = -104

16x + 4y = -96

____________-

-8x = -8

x = -8/-8

[tex] \boxed{x = 1}[/tex]

Substitute x

4x + y = -24

4(1) + y = -24

4 + y = -24

y = -24 - 4

[tex] \boxed{y = - 28}[/tex]
