Answer:
x = -6
y = 24
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
