Answer:

x=-2

y=1

Step-by-step explanation:

Rewrite first equation to get:

[tex]x=-\frac{2+4y}{3}[/tex]

Substitute into second equation:

[tex]6\left(-\frac{2+4y}{3}\right)+6y=-6[/tex]

[tex]-2y-4=-6[/tex]

[tex]y=1[/tex]

Substitute y=1 into any equation:

[tex]x=-\frac{2+4y}{3}[/tex]

[tex]x=-\frac{2+4\cdot \:1}{3}[/tex]

[tex]x=-2[/tex]
