This research is to improve problem-solving skills in SMP Muhammadiyah 8 Medan students through Polya learning theory in the material of linear equation systems in two-variable. This research method is Classroom Action Research. The research subjects were class VIII SMP Muhammadiyah 8 Medan totalling 29 students. The object of research is the ability to solve mathematical problems - data from research results obtained from observation and test results. The results showed that the use of Polya learning theory could improve students' mathematical problem-solving abilities. In the pre-cycle, there was 10.34% (3 students) of the 29 students who achieved the passing grade. The test results in cycle 1 showed there was 51.72% (15 students) of the number of students who reached passing grade, whereas in cycle 2 there was 75.86% (22 students) of the number of students who reached passing grade.
