Answer:
x=-5, y=-11
Step-by-step explanation:
When approaching systems of equations, you must either solve via subsitution or through manipulation to get one term aglebraically; either way, you want to solve for one variable at a time. So, we have
[tex]y=6-x \\and \\y= 3x+4[/tex]
Multiply line A by (3) and then add it on to Line B. From there break it down and sub in what you get for y into either equation.
