sburchette · Answer

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.

anonymous · Answer

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)

redprince · Answer

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

anonymous · Answer

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

@dplanc yes you are right!
