Hello:

I have already found references "optim" ,
but I do not understand its means !!
So I want to ask next question
I have a question in Math.
If we want to get X's and Y's solution, X>0 and Y>0
We have two equation :

2*exp(X)+X^2+3*Y=2*exp(1)+4
3*exp(X/Y)+3*X*Y+4*Y=3*exp(1)+7

How I use R-project to  solve above question??

THANKS  YOU !!!!
THANK YOU VERY MUCH!!
                                                HLC
