<cfAbstr cfLangCode='EN' cfTrans='o'><p>We find conditions for a singular point O(0,0) of a center or a focus type to be a center, in a cubic differential system with two distinct invariant straight lines. The presence of a center at O(0, 0) is proved by using the method of Darboux integrability and the rational reversibility</p></cfAbstr>
