The figure represents a street plan for a city block in the U.S. Suppose all streets have one-way traffic. The arrows represent the one-way direction of each street and the numbers are the numbers of vehicles per hour that pass through these streets. Please write out your equations for this linear system using the condition: in-flow = out-flow, for each of the crossing nodes denoted by A B C D E and F. For example for A: 200+x6=x1+400. Solve the equations when X6=300 and X7=200 using one of the methods we learn to solve, i.e. NGE or GE P.P or LU
