Answer
The solution is $(-1,2)$.
Work Step by Step
The given system of linear equation is
$9x+3y=-3$ ...... (1)
$2x-y=-4$ ...... (2)
Graph each equation.
The intersection point is $(-1,2)$.
Check the intersection point.
Equation 1:
$\Rightarrow 9x+3y=-3$
$\Rightarrow 9(-1)+3(2)=-3$
$\Rightarrow -9+6=-3$
$\Rightarrow -3=-3$
True.
Equation 2:
$\Rightarrow 2x-y=-4$
$\Rightarrow 2(-1)-2=-4$
$\Rightarrow -2-2=-4$
$\Rightarrow -4=-4$
True.
The solution is $(-1,2)$.
