A singular initial value problem for a system of integro-differential equations of the first order unsolved with respect to the derivative of the unknown functions is considered. It is shown that under certain assumptions there is a solution lying in a region, having the vertex coinciding with the initial point, in which the graph of a solution of given singular problem is located. The main result gives asymptotic estimates of a solution and its derivative with respect to a general solution of an auxiliary differential equation. An approach which combines topological method of T. Wa?ewski and Schauder¡¯s fixed point theorem is used. The results generalize some previous ones, where the singular initial value problems for integro-differential equations were studied.
