I do not understand what "new values at e5" means. Currently e5 is [y=0] (see output %o5). That makes
input (%6) equivalent to solve([y=0], x). Because there are no values for x that satisfy the equation y=0,
Maxima gives the empty list (not an error) as output in (%o6).

I don't see a problem. What am I missing?
