Abstract	Solving systems of equations at school, at least in Argentina, is usually a task that students are given as a series of techniques that "allow" them to find a solution. How to overcome educational obstacles that are generated from a fragmented approach of knowledge? What can DGS do, in particular the CAS environment? What epistemic and instrumental value (Artigue, 2002) these techniques acquire to work with software? Do they redefine work with pencil and paper? Specifically, this paper attempts to examine a series of dynamic problems (Bifano andVillella, 2012) and study the manipulation of different parts of the same equations and reflections that have emerged from experience working with teachers who analyse and solve such problems. Using the notion of instrumental orchestration (Trouche, 2004) we considered the different types of didactical performance as a result of the workshop experience. (As Provided).
