%X Modeling  is one of abilities  included  in studying  mathematical materials. Modeling   is mostly used to express the events of everyday life , such as  modeling  of  tsunami  wave,  modeling  of  population  growth,  and  modeling  of  economics  growth.   Therefore,  mathematical  modeling  is  an  important  ability  to  be  possessed  by  students. It is  in line  with the  opinion  of  Niss  (2010)  who  states  that  Modeling  is  a  Crucial  Aspect  of  Students'  Mathematical  Modeling.  Considering  its  significance,   mathematical  modeling  should  be learned  by  students  since  they attend  elementary  school. For example,  Singapore  school  curriculum  has provided an opportunity  for   students  to  learn  mathematical  modeling  abilities  since  they  attended  elementary  school  (Kaur  and  Dindyal,  2010).  On the other hand, it is a fact that  students  -  in  some  countries,  such  as  Germany,  England,  Romania,  Canada,  Czech  Republic,   Mozambique,  Netherlands,  and  Japan  -  have difficulties in  mathematical  modeling  (Ikeda,  2007).  Therefore,  this paper  is intended to  discusse  some difficulties faced   by  junior  high  school  student  in  conducting  mathematical  modeling  and  model   interpretation,  particularly  in  the  materials  of    linear  equation  system  of  two   variables. Data  were obtained from students in two junior high schools coming from  two and three cluster schools in the Bandung Municipality, covering research subject  as many as 151 students.
