**Solving a system of 3 equations and 4 variables using**

A system of linear equations is a set of linear equations with the same variables. There are two types of special systems of linear equations; those with no solution and those with infinitely many... In this chapter we will look at solving systems of differential equations. We will restrict ourselves to systems of two linear differential equations for the purposes of the discussion but many of the techniques will extend to larger systems of linear differential equations. We also examine sketch phase planes/portraits for systems of two differential equations. In addition, we give brief
