Abstract : It is shown in this report that the solving of differentialdifference equations of specific class can be presented in form of a sum of two components, the first one of which is solution of a certain difference equation, and the second one sum of solutions of a certain recurrent system of differential equations. Such a concept allows easily to find accurate solutions of differentialdifference equations, without resorting to the determination of roots of corresponding transcedental characteristic equations. A concrete example is given. The proposed method appears to be one of the variants of a combination of a known step method and Laplace transform.
