I don't know enough if this is a repeat somewhere else:

fricas
```solve([x**3+y**3+cot(z)=12,x**2+z=1101,x*y=53],[x,y,z])
There are no library operations named **
Use HyperDoc Browse or issue
)what op **
to learn if there is any operation containing " ** " in its name.
Cannot find a definition or applicable library operation named **
with argument type(s)
Variable(x)
PositiveInteger
Perhaps you should use "@" to indicate the required return type,
or "\$" to specify which version of the function you need.```

gave:: WARNING (genufact): No known algorithm to factor 6 3 ? + (cot(z) - 12)? + 148877, trying square-free.

>> Error detected within library code: No identity element for reduce of empty list using operation append

Similarly:

``` solve([x+cot(z)=12,x+z=0],[x,z])
2) ->
>> Error detected within library code:
No identity element for reduce of empty list using operation
append
```
