"Eu nu aș merge cu voi."
Translation:I would not go with you.
Depends. If you say "I would not walk with you to the park" then yes, it is WALK. If you say "I would not go with you to Malta" then it is used GO. GO is most used when you have to go in far places, when WALK is used when you can only... WALK beacuse is close to you ;)
