Answer:

-2x-7y-7z

Step-by-step explanation:

I'm going to start off by separating the different variables and keeping the sign in front with it.

(5x-3x-4x) + (-6y+2y-3y) + (-7z-z+z)

After that it's simply solving a simplifying.

(-2x) + (-7y) + (-7z)

And your final answer should be...

-2x - 7y - 7z!

Hope I helped!
