I have the following small piece of Mathematica code that works fine for 
my purposes.

 BInv = {{  1/4, 1/4, 0},
              {-1/2, 1/2, 0},
              {  3/4, -5/4, 1}}
 B = Inverse[BInv]
 b = {4 + \[Delta], 8, 10};
 BInv.b // FullSimplify
 Reduce[{%[[1]] >= 0, %[[2]] >= 0, %[[3]] >= 0}, {\[Delta]}]
 % /. {\[Delta] -> b1 - 4} // FullSimplify

which gives

0 <=  b1 <= 8

which is of course correct. But, how can I use (access) the values 0 and 8?
That is, I would like to now use these values in some expressions that 
would follow this.

Thanks,
V. Stokes
