In this paper, an analytical approximate solution of a system of fractional differential equations, fractional heat-like two-dimensional equation and stiff system of nonlinear differential equations is obtained using variational iteration method. The results reveal that our method is effective straightforward and very simple. The numerical findings for different cases of problems are presented graphically. The results reveal that the variational iteration method is convenient, stable, efficient, much easier and performs extremely good in terms of simplicity and efficiency.
