Question

Consider the traffic flow diagram that follows,
where a1, a2, a3, a4, b1, b2, b3, b4 are fixed positive
integers. Set up a linear system in the unknowns
x1, x2, x3, x4 and show that the system will be
consistent if and only if
a1 + a2 + a3 + a4 = b1 + b2 + b3 + b4
What can you conclude about the number of
automobiles entering and leaving the traffic
network?
