Answer:

x = -6

y = 24

Step-by-step explanation:

The system of equations is:

y = -8x - 24

y = -4x

To solve by subtritution, we need to substitute y = -4x on the first equation to get:

y = -8x - 24

-4x = -8x - 24

So, solving for x, we get:

-4x + 8x = -8x - 24 + 8x

4x = -24

4x/4 = -24/4

x = -6

Then, we can find the value of y as:

y = -4x

y = -4(-6)

y = 24

So, the solution of the system is x = -6 and y = 24
