In this papers,He’s variational iteration method(VIM) is implemented to for solving analytically systems of nonlinear ordinary differential equations such as modelling the pollution of a system of lakes. The proposed scheme is based on variational iteration method (VIM), Laplace transform and Padé approximants. The results to get the variational iteration method (VIM) are applied Padé approximants. Our proposed approach showed results to analytical solutions of nonlinear ordinary differential equation systems. The results are compared with the results obtained by MATLAB ode15s and the variational iteration method (VIM) are applied Padé approximants. Some plots are presented to show the reliability and simplicity of the methods.
