Answer:

x-5y=12 and
3x+2y=-15

Explanation:

The first system is

x-5y=-12 and
3x+2y=-15

We substitute x=-3 and y=-3

$-3-5*-3=12\\e-12$ and
3*-3+2*-3=-15

Both equations are not satisfied

The next system is

x-5y=12 and
3x+2y=-15

We substitute x=-3 and y=-3

-3-5*-3=12 and
$3*-3+2*-3=-15\\e15$

Both equations are satisfied

The next system is

x-5y=-12 and
3x+2y=15

We substitute x=-3 and y=-3

$-3-5*-3=12\\e12$ and
3*-3+2*-3=-15

Both equations are not satisfied

The next system is

x-5y=12 and
3x+2y=15

We substitute x=-3 and y=-3

$-3-5*-3=12\\e-12$ and
3*-3+2*-3=-15

Both equations are not satisfied
