Step-by-step explanation:

use substitution method so it will now look like

8x + 5(-4x) = 24

8x + (-20x) = 24

-12x = 24 (divide both sides by 12)

-x = 2 (multiply both sides by negative 1)

x = -2

substitute to find y

y= -4(-2)

=8

Answer:

[tex]x=-2\\y=8[/tex]

Step-by-step explanation:

[tex]8x+5y=24\\y=-4x[/tex]

We already have y in terms of, so the easiest way to do is by plugging that value in the first equation.

[tex]8x+5y=24\\8x+5(-4x)=24\\8x-20x=24\\-12x=24\\x=\frac{24}{-12} \\x=-2[/tex]

After having found the value of x, replace it in the second equation to find y.

[tex]y=-4(-2)\\y=8[/tex]
