The classical wave equation in the space of generalized functions (distributions)is considered. The Distributions Method of building the solutions of nonstationary boundary value problems (NBVP) for wave equations in coordinates spaces of different dimensions is elaborated. Dynamic analogues of Green and Gauss formulas for solutions of wave equation in the distributions space are built. Their regular integral representations and singular boundary integral equations for solving the nonstationary problems are constructed for the coordinates spaces of the 1,2,3-dimensions. The method of obtaining of conditions on shock waves fronts is stated. The theorem on the single solution of NBVP is proved, including shock waves.
