This article offers a method for teaching the solution of equations and their systems using the GeoGebra computer program. Namely, the graphical solution of equations not only in the classical case when the equations or their systems have one or more solutions, but also when they do not have a solution. Clearly showing the solutions of these examples of systems of equations, we can talk about a higher assimilation of educational material by students. It will also allow you to optimize the learning process, more efficiently using time at different stages of the lesson; to implement a differentiated approach to learning; conduct individual work using personal computers; reduce emotional stress in the lesson, introducing an element of play; expand the horizons of students; contributes to the development of cognitive activity of students.
