2. The figure below represents the traffic entering and leaving a roundabout road junction in Continental Europe. Such roundabouts ensure the continuous smooth flow of traffic at road junctions. Construct a system of linear equations describing the flow of traffic along the various branches. Use these equations to determine the minimum flow possible along xị. What are the other flows at this time? Explain what happens to x7 traffic. It is not necessary to compute the reduced echelon form. Use the fact the traffic flow can't be negative. The traffic is measured in vehicles per hour (vph). 90 A100 X3 X2 155 130 XA 120 110 X6
