On Dual Equations with Four Unknowns x – y*z = k * z3, x*y=w3

Abstract: This paper discusses on finding integer solutions to the system of double equations with four unknowns given by 33 *,** wyxzkzyx ==− . Four choices of integer solutions to the considered dual equations are presented. Employing the obtained integer solutions, the process of formulating Second order Ramanujan numbers is illustrated.
