a The figure shows die intersections of a number of one-way streets. The numbers given represent traffic flow at a peak period (front 4 p.m. lo 5:30 p.m.). Use the figure lo write a linear system of six equations in seven variables based on the idea that at each intersection the number of cars entering must equal the number of cans leaving.
