Find the general flow pattern of the network. Assuming that the flows are all nonnegative, what is the smallest possible value for $x_4$?

Points of Intersection: Flow In = Flow Out

A: $x_1+x_4 = x_2$

B: $x_2 = x_3 + 100$

C: $x_3 + 80 = x_4$

The total flow in equals the total flow out, so you can set up other equations...

How do I turn this into a solvable matrix to get the answer?
