5. (15 points) One application of linear systems of equations is traffic analysis. Below is a diagram of part of the Inner Harbor area of Baltimore. The problem you want to explore is the amount of traffic among the eight intersections (labeled A, B, H). The arrows indicate the direction of traffic. Each street is a one-way street. The numbers indicate the number of vehicles (per hour) that enters or leaves an intersection. For example,...
