Rewrite the equation in new form: from y = f(k) to k = g(y)

Dear all,
I wonder how to do the following with Mupad:
- If I have an equation like y = (1-delta)/(1+n) + sigma*{(1+alpha)^t}/{(1+n)*k^(1-theta)} where k is variable, i.e, y = f(k). - I want to rewrite in term of variable k, saying, k = ... or k = g(y).
How to do that with Mupad functions. Thank you and best regards,

In general, you cannot do so. This is what solve does (for the symbolic TB), but it is severely limited, as must be any such tool.
For example, consider the function
y = x^2
There is no single valued function of the form
x = f(y)
for that very simple relationship.
