The solution to a system of linear equations is (-3,-3) Which system of linear equations has this point as its solution? x -5y=-

Ann [662]

Answer:

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

Step-by-step explanation:

The first system is

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

We substitute x=-3 and y=-3

$-3-5*-3=12\ne-12$ 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 $3*-3+2*-3=-15\ne15$

Both equations are satisfied

The next system is

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

We substitute x=-3 and y=-3

$-3-5*-3=12\ne12$ 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

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