    You first solve for x or y in one equation and then substitute it into the other equation. I would say it is easiest to solve for either y in the first equation or x in the second equation.

    substitue... solve for y in the first equation then put that expression into the second equation.... these equations are parabolas.... at most, they will have 4 solutions (intersections)

    is there any other way to solve these equations!!! I solve these equations to find out local maximum, minima and siddle point!!!

    so you're not looking for solution(s) to this system? you just want the max/min of these parabolas?
