Question: complicated simultaneous equations

Hi, i am trying to solve the equations denoted eq1 and eq2 for x and r.

f:=r*(8 - 2*x^2);
eq1:= g-x:
eq2:= expand(diff(g,x) + 1):

I am having a bit of trouble as these simultaneous equations have many solutions and using the command solve, just basically crashes maple. I just want the commands that would give the positive set of solutions only, ie. excluding all complex and negative solutions. 

Thanks in advance.
