1. The problem statement, all variables and given/known data the following statement shows the traffic flow(in cars/minute) along 3 one way streets through the intersections A, B and C Set up and solve a system of linear equations(using the augmented matrix for the system) to help you find the flows x,y and z. Be sure to generate the RREF of the system a link of the drawing: http://img18.imageshack.us/img18/2276/trafficflow.jpg [Broken] 2. Relevant equations traffic flow in must equal flow out 3. The attempt at a solution so to start things off, equations i put: 3 + z = 3 6 + x = 7 5 + y = 4 is this at all right?
