This study aims to determine the difficulties experienced by students and the factors that cause difficulties in solving mathematical problems in a system of linear equations in two variables (SPLDV) material. The Study method used was qualitative descriptive research with class VIII students at MTs Wali Songo Sukajadi Lampung as the subject. This study uses observation, interviews, and written tests to collect data. Data reduction, presentation, and conclusion are used as data analysis techniques in this research. The results showed several types of difficulties experienced by students, including difficulties in understanding concepts, difficulties in applying mathematical models to problems, and difficulties in applying algebraic operations. Difficulties in applying numerical models to problems and difficulties in applying mathematical tasks. Based on these data, several factors become obstacles for students in solving math problems, including Students who are in a hurry to solve problems, are not careful, do not understand concepts, and lack knowledge of algebraic operations.
