This article has been retracted at the request of the Editor-in-Chief. In summary: the name of one author was removed during the submission process. The editors, therefore, feel that the findings of the manuscript cannot be relied upon. In this paper, we applied an extension of the optimal homotopy asymptotic method (EOHAM) for the approximate solution of coupled partial differential equations (PDEs). The obtained results are compared with other results for its efficiency. The order of convergence and residuals are plotted.
