This research method is a qualitative descriptive research. Data collection was carried out using written tests and interview methods. The research subjects were taken from 30 students in grade VIIID of Widya Sakti Junior High School, Denpasar.

Based on the results of the study, it can be concluded that the types of errors that arise when students solve SPLDV questions are 1) Mistakes in understanding the questions, which include not writing down what is known in the questions, and not writing down the things asked in the questions. 2) Transformation errors that include not understanding the solution method used. 3) process capability errors, which include not completing the process. 4) Final Answer Writing Errors, which include not writing the final answer in the question. The factors that cause student errors are students who are not careful in doing problems, students who are too hasty, and students who do not practice story problems.
