The `solve`

command looks for an analytic solution. In this case, the solution will involve the Lambert W function, `lambert_w`

. For some reason, though, Sage is not finding it. (You need to use `to_poly_solve=True`

in the `solve`

command, but Sage is encountering an error.)

To find approximations of the solutions, you can use `find_root`

.

For example,

```
find_root(-V+exp(V)-0.5*V-1,-1,0.5)
```

and

```
find_root(-V+exp(V)-0.5*V-1,0.5,1)
```

give the two roots.
