The exact solution of two-equation system of second-order nonlinear ordinary differential equations is obtained in the reproducing kernel space W23 [0,1]. The exact solution is represented in the form of series. The n-term approximation un (x), vn (x) are proved to converge to exact solution u (x),v(x). More importantly, the method's implementation requires no additional conditions, whether the equations are singular or non-singular and linear or nonlinear. Examples are presented to demonstrate the reliability and efficiency of the algorithm developed.
