Simple Simulation

Hi, I have a simple problem but I don't know how to solve it..where to start from..the things I read have stochastic simulation...but what I want is direct: I'm trying get the values of X and Y for which the conditions below are verified:

initial/final values for X [0,20] and for Y [0,10]

1. ((Y+1)^2 / Y)- 1 <= X

2. X<= (Y+2)^2/ (Y+1)

and knowing the values of X and Y, if these values verify:

delta [0,1]

delta >= ((X-1)^2 (Y+X+1)^2) /(X+Y+1)^2(X+1)2^-16X^2(Y+1)

and obtain a table where I have

            condition 1 | condition 2 | the value of delta |

X = , Y =.. True/False | True/False | |

What do you advise to read? where can I learn how to do it?

thanks
