Answer:

$(-4,-5 )$

Step-by-step explanation:

You are looking for the point of intersection of these two functions.

Substitution:

This are now your formulas

$\left \{ {{x=-4y-24} \atop {5x+3y=-35}} \right.$

You are going to substitute x, so you can solve for y

$5(-4y-24)+3y=-35$
$-20y-120+3y=-35$
$-17y=85$
$y=-5$

Now you are going to substitute y to find x

$x=-4(-5)-24$
$x=20-24$
$x=-4$

Now lets check if it is correct

$-4+4(-5)=-24 :)$
$5(-4)+3(-5)=-35 :)$

So it is true, making (-4 , -5) your point of intersection.

hope it helps
