This paper investigates the solitary wave solutions of the 2+1-dimensional regularized long-wave 2DRLG equation which is arising in the investigation of the Rossby waves in rotating flows and the drift waves in plasmas and 2+1 dimensional Davey-Stewartson DS equation which is governing the dynamics of weakly nonlinear modulation of a lattice wave packet in a multidimensional lattice. By using extended mapping method technique, we have shown that the 2DRLG-2DDS equations can be reduced to the elliptic-like equation. Then, the extended mapping method is used to obtain a series of solutions including the single and the combined non degenerative Jacobi elliptic function solutions and their degenerative solutions to the above mentioned class of nonlinear partial differential equations NLPDEs.
