Consider the traffic flow diagram that follows, where a1, az, a3, 24, 61, 62, 63, 64 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 + 24 = 61 + b2 + b3 + 64 What can you conclude about the number of automobiles entering and leaving the traffic network? ai ba bi X1...
