abstract = {In the present paper, we examine the existence of solutions to fourth-order differential equation systems when the  L1-Carathéodory function is on the right-hand side. A concept of solution-tube for these issues is presented. The concepts of upper and lower solutions for fourth-order differential equations are extended to systems owing to this idea.}
