This article deals with the students problematic when solving systems of linear equations with two variables by applying different resolution methods. Concerning the interpretation and use of the obtained results, it is identified that linear equations by themselves become an obstacle, because they make difficultthe comprehension of the foregoing. To overcome this obstacle, for the resolution of equation systems, the Raymond Duval’s theory of semiotic representations is proposed, because the complications of the register conversion operation are overlooked, without associating the related elements.
