Bess [88]

Answer:

0

Step-by-step explanation:

So we have the expression:

$\frac{2x+y}{xy-2x}$

And we want to evaluate it for x=-4 and y=8.

So, substitute:

$\frac{2(-4)+(8)}{(-4)(8)-2(-4)}$

Multiply:

$=\frac{-8+8}{-32+8}$

Add:

$=\frac{0}{-24}$

Evaluate:

$=0$

So, our answer is 0.

And we're done!
