Abstract
The purpose of this study was to determine the alleged learning trajectory of the two-variable linear equation system (TVLES) through learning by applying a problem based learning model to class VIII junior high school students. Learning mathematics requires a meaningful process and that process cannot be obtained in a relatively short time because it requires good preparation in conveying mathematical concepts to students. The preparation is designed according to the characteristics of students so that the delivery of the material goes well as expected. The preparation referred to in this case is to design a good hypothetical learning trajectory (HLT). Hypothetical learning trajectory (HLT) is a temporary hypothesis about students^ activities in the learning process on certain materials. This study used research design and only in the preliminary step which was structured using a problem-based learning process (PBL). Every student in learning has a different way of thinking. This paper describes the hypothetical learning trajectory (HLT) in student learning activities on the material of a two-variable linear equation system (TVLES) through a problem based learning model
