By extending homogeneous balance method and improving some of its procedures, we have obtained new multi-soliton-like solutions for (2+1)-dimensional dispersive long-wave equations and (2+1)-dimensional Broer-Kaup equations- The solution we obtained presents generality, because it contain some multisoliton-like solutio ns which are given in other papers--
