This research aims to produce a description of the learning obstacles experienced by students in solving systems of linear equations in two variables problems related to mathematical communication abilities. This research used a qualitative research method. The research subject were 30 students of eighth grade students in class in one junior high school in Padangsidimpuan, North Sumatera. The results showed that most students experienced learning obstacles that were ontogenic, didactic, and epistemological in solving systems of linear equations in two variables related to mathematical communication abilities, based on the identification of mathematical communication abilities and the problems experienced by students in solving systems of linear equations in two variables problems. This is because the student are hampered by their ability to learning about the system linear equation of two variables, incomplete and limitations of the context systems of linear equations in two variables and inability to use concept systems of linear equations in two variables in the context of non-routine questions that are not the same as the context of questions given by their teacher. This study produces information about the causes of the obstacle experienced by students in solving systems of linear equations in two variables. © 2023 Author(s).
