We using this transformation to solve differential equations. We applied Laplace decomposition method and Elzaki decomposition method to solution for nonlinear partial differential equations. We solved some problems(Partial, System of DES and Integral Equations) using Laplace transform and Elzaki transform, and then compared the solutionsenPartial Differential EquationsThesis
