Question 992935
.
You want to solve using substitution.
{{{system(4x-3y=-6,
-x-2y=7)}}}


Simplest may be
{{{-x=2y+7}}}
{{{x=-2y-7}}}
Now substitute into the other equation.
{{{4(-2y-7)-3y=-6}}}
{{{-8y-28-3y=-6}}}
{{{-11y=-6+28}}}
{{{-11y=22}}}
{{{y=-2}}}
{{{highlight(y=-2)}}}


{{{x=-2y-7}}}
{{{x=4-7}}}
{{{x=-3}}}
{{{highlight(x=-3)}}}
