Answer:

[tex]y=5[/tex]

Step-by-step explanation:

we have

[tex]x-y=-11[/tex] ----> isolate the variable x

[tex]x=y-11[/tex] -----> equation A

[tex]y+7=-2x[/tex] ----> equation B

substitute equation A in equation B

[tex]y+7=-2(y-11)[/tex]

solve for y

[tex]y+7=-2y+22[/tex]

[tex]y+2y=22-7[/tex]

[tex]3y=15[/tex]

[tex]y=5[/tex]
