Solving these systems of equations involve more complex algorithms and data structures than their dense counterparts. A system of n linear equations has the following form: In matrix notation, this system can be represented by, where A is the matrix of coefficients such that, b is an vector. and x is the desired solution vector.

The model for this example was put together by looking at the inputs as well as the constraints, as stated by the company. The basic concept of deriving this model is simply related to building a system of equations exactly how one would build a linear system of equations for a model to be solved in linear/matrix algebra mathematics classes.
