Question 827976
The system is partly setup for you.  Second equation is a formula for x.  Substitute it into the first equation and find the value for y.


{{{x+4y=-6}}}
{{{(5-y/3)+4y=-6}}}
{{{-y/3+4y=-6-5}}}
{{{4y-y/3=-11}}}
{{{(4-1/3)y=-11}}}
{{{(12/3-1/3)y=-11}}}
{{{(11/3)y=-11}}}
{{{highlight(y=-3)}}}
Find x from this.
