In this paper the authors study linear systems of first-order partial differential equations u{sub x} + Au{sub y} + Bu = O, where A and B are given constant square matrices and u is an unknown vector-valued function with values in an m-dimensional real or complex vector space. We exhibit cases in which the general solution of the system (1) can be expressed in terms of solutions of coupled second-order partial differential equations and the derivations of these solutions. Then the solution of boundary-value problems for the system (1) with a boundary condition of the form u = f reduces to the successive solution of boundary-value problems of the same type for such equations. 1{degree}. Consider the simplest special case of the system u{sub x} + Au{sub y} = O. We shall assume that A is a complex-valued matrix and u a complex-vector-valued function.
