Answer:

The Answer would be (x, y)=(-8, 24).

Explanation:

First, Solve the equation for x = -8

Substitute the given value of x into the equation. -9x - 5y = -48

-9x(-8)-5y=48

Solve the equation for y.

y=24

The Possible Solution of the system is the ordered pair. (x, y)

(x, y)=(-8, 24)

Check if the given ordered pair is the solution of the system of equation.

-3x(-8)=24

-9x(-8)-5x24=-48

Simplify the qualities.

24=24

-48=48

Since all of the equalities are true, the ordered pair is the solution of the system.

Solution:

(x, y)=(-8, 24)
