Answer:

y=-4

x=-3

Step-by-step explanation:

6x+2y=-26 (equation 1)

-6x+36y=-126 (equation 2)

38y=-152

Both side divide by 38

[tex]\frac{38}{38}[/tex]y=[tex]\frac{-152}{38}[/tex]

y=-4

substitution y=-4  in(equation 1)

6x-8=-26

6x=-18

x=-3

substitution y=-4  in(equation 2)

x+24=21

x=-3
