rhs method returning empty sym

I am unable to use the function rhs to extract RHS of symbolic equations

Code written:

syms x; rhs(x==5)

This returns

[ empty sym ]

Is there something that I am missing here?

Possible reason is that you may have created a variable/file named rhs , please clear it.
