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

## Homework Equations

traffic flow in must equal flow out

## 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?
