An electronics company produces three models of stereo speakers, models A, B and C, and can deliver them by station wagon, truck, or van. A station wagon holds $3$ boxes of model A, $3$ boxes of model B and $2$ boxes of model C. A truck holds $7$ boxes of model A, $6$ boxes of model B and $4$ boxes of model C. A van holds $4$ boxes of model A, $3$ boxes of model B and $2$ boxes of model C. If $23$ boxes of model A, $21$ boxes of model B and $14$ boxes of model C are to be delivered and the owner wants each vehicle to operate at full capacity, the parameterized solution to the resulting system of equations is: $(z+3,-z+2,z)$. for (station wagons, trucks, vans). Use the parameterized solution to find the possible configurations of vehicles.
How to use parameterized solution to find solutions?

1Please don't post questions in the imperative mode, as if giving orders or giving out an assignment. Also, please don't use the title as an integral part of the question, use the body of the question for that. It helps a lot if you say where you are stuck and why. – 2011-02-07
