Vosoughi 1 Department of Applied Mathematics, Lahijan Branch, Islamic Azad University, Lahijan, Iran Unfailing real world problems in engineering, economics, finance, etc. can lead to solving a system of linear equations. 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.
