Systems of Equations: Substitution Method

This video is the first of three videos that appear the title of "Systems of Equations." I wanted to hang these three videos for you to understand better how analytically reuelven systems of linear equations.
In the videos, a professor at the Polytechnic University of Cartagena, "count" how reuelve the same system of equations by three different methods (Replacement, Reduction and Equalization). As seen with the three methods achieve the same solution. Thus, any of them will be suitable to get solve a system of linear equations. After seeing it, I hope practiquéis, for that is really going to learn to solve systems of equations.
