Hey there!
[tex]\boxed{x=1;y=4}[/tex]
[tex]3x + y = 7 \\ \\
6x + 4y = 22[/tex]
[tex]y = -3x + 7 \\ \\ Plug \ this \ in \ for \ variable \ (y) \ in \ equation \ \\ \\
6x + 4*(-3x+7) = 22 \\ \\
-6x = -6 \\ \\ 6x=6 \ x+1 \\ \\ x=1 \ y=-3x+7 \\ \\ \boxed{y=-3(1)+7=4} \\ \\ \boxed{\boxed{x=1;y=4}}[/tex]
I hope this helps you!
