What is the question you're having problems with?

When I work out from the piovt rows 2, 3 & 4 work out the same and I not sure about x,y,z &w being non negative, some of my values are negative.

I mean specifically post the question you're having problems with. I can hardly guess what the problem is without seeing what the question is and what you've done. Then we'll see what we can do!

You appear to be right; the solution has some values negative. This means that the routes are not all 1-way.
