-8y=6

Answer:

[tex]-8y=6[/tex]

Step-by-step explanation:

The given system of equations is;

[tex]-6x+4y=-8[/tex]

and

[tex]6x-12y=14[/tex]

If we add the two equations, we get;

[tex]-6x+6x+4y+-12y=-8+14[/tex]

We combine the similar terms to obtain;

[tex]0-8y=6[/tex]

This simplifies to;

[tex]-8y=6[/tex]
