Answer:
Step-by-step explanation:
plug y into the first equation:
8x+5y=24
8x+5(-4x)=24
8x-20x=24
-12x=24
x=-24/12
x=-2
then plug x to the second equation
y=-4
y=-4(-2)
y=8
8x + 5y = 24
You just told us that Y = -4x .
If that's true, then
8x + 5(-4x) = 24
8x - 20x = 24
-12x = 24
x = -2
y = -4x
y = -4(-2)
y = 8
