    You probably meant y’’ + y = x

    This is just a second-order linear ordinary differential equation with solution

    y = Asin x + Bcos x + x

    Using the variation of parameters method would be using a sledge hammer

    to crush a walnut; however a demonstration of that method with a similar example can be found here.
