Chapter 1, Problem 16(choose chapter or problem)
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?
