Answer:

(6,2)

Step-by-step explanation:

Since [tex]y=x-4[/tex], we can substitute this into the second equation so that there is only one variable that we can solve for.

[tex]4x+(x-4)=26[/tex]

[tex]5x-4=26[/tex]

[tex]5x=30[/tex]

[tex]x=6[/tex]

Now we can plug this back into the first equation.

[tex]y=(6-4)[/tex]

[tex]y=2[/tex]
