This study aims to describe the reflective students' critical thinking process in solving the problem of two-variable linear equation system. Instruments used to know the critical thinking process of the subject is a problem-solving test and interview. Through tests and interviews, we can analyze the critical thinking process of the subject based on six criteria focus, reason, inference, situation, clarity, and overview. The results showed that both subjects only met the criteria of focus, and experienced errors in making mathematical models, so that both are not able to solve the problem.
