Hello There today we solve your problem
Since you mean't the equation
[tex]y-4=x\\y+2x=-2[/tex]
we will use that one instead
First off we can substitute [tex]y[/tex] for [tex]x+4[/tex]
Now we have an equation
[tex]x+4+2x=-2[/tex] then simplify
[tex]3x+4=-2[/tex]
do simple algebra and we get that
[tex]x=-2[/tex]
Since we said that [tex]y=x+4[/tex] we can plug in our value of [tex]x[/tex]
[tex]y=-2+4\\y=2[/tex]

[tex]\boxed{x=-2}[/tex]
[tex]\boxed{y=2}[/tex]
