Question

What is -2x-x+8 I'm too tired to do this lol

Answer 1

You can sum the two terms involving x:

$-2x-x+8=-3x+8$

There's nothing else we can do with this expression. If you need to find its root, we have

$-3x+8=0 \iff 3x=8 \iff x=\dfrac{8}{3}$

Answer 2

The correct answer to this would be -3x+8
