&[DATE] &[TIME] - &[FILENAME]

What I am trying to do is substitute x somewhere further in the notebook...

eq x 2^x + 10 - :

res eq 0 ≡ x Solve :

res 11 el x 141 sqrt + 2 / - (≡

res 21 el x 1 - 41 sqrt + 2 / ≡

Now i want to substitute first root into:

eq2 x 5 + :

eq2 res 11 el at #

however...

eq2 x 141 sqrt + 2 / - (≡ at 1.2984

What am I missing here?
