In this paper we give a survey a new approach to solve this problem based on homotopy perturbation method. Furthermore, we show that the solving linear equations by using a new method called modified homotopy perturbation method, presented in [M.A. Noor, K.I. Noor, S. Khan, M. Waseem, Modified homotopy perturbation method for solving system of linear equations. Journal of the Association of Arab Universities for Basic and Applied Sciences., 13(2013)35-37] is impractical.
