In Algebraic entry mode you need a comma to separate the entries.

In both case the stack represents them without a comma.

I think what puzzled you is that I did not write any commas in my first answer fsolve([eq1 eq2], [x y])

The help sections for fsolve and solve are a bit confusing, especially the one for solve because it doesn’t mention the ExpVector form of the command, even if an example with 3 equations involving x, y and z as variables is given.

PS (off topic): I sometimes write “numerical solution”, and sometimes “numeric solution”. What’s the right word?

It depends haven't seen examples of either from you to say that one is right or wrong.
I would say a numerical solution: that's an article that will help decide.
