The aim of this paper is to show the use of the coupled quasisolutions method asa useful technique when dealing with ordinary differential equations with functionalarguments of bounded variation. We will do this by looking for solutions for a first-order ordinary differential equation with an advanced argument of bounded variation. The main trick is to use the Jordan decomposition of this argument in a nondecreasingpart and a nonincreasing one. As a necessary step, we will also talk about coupled fixed points of multivalued operators
