Thank you!

The figure on the right shows the intersections of three one-way streets. Use Gaussian elimination to solve the system of equations that models this situation (shown below). 8 7 Cars/min Cars/min x + 8 = y + 15 15 12 z + 12 = x + 7 Cars/min Cars/min y + 22 = z + 20 22 20 Cars/min Cars/min Select the correct choice below and fill in any answer boxes within your choice. A. There is one solution. The solution set is {( . .| |} (Simplify your answers.) O B. There are infinitely many solutions. The solution set is { ( .|,z) ), where z is any real number. (Type expressions using z as the variable.) O C. There is no solution
