find min of Sqrt((x-14)^2 + (y-55)^2) + Sqrt((x-23)^2 + (y-95)^2)

Or any application which can help finding this kind of problem?

This is a multivariate calculus problem with the function f(x,y) = z, where z is the unstated dependent variable for the equation you gave for the third z-axis.

Are you a teacher? If not, you should be. Even I understood your explanation!
