Question: are we talking Python or JavaScript?
So we have x ++ equals in Python:

But in Python the comma would create a tuple.
Exactly, just as driving on the left side of the road will be fine in
some countries but cause a crash in others. Learn the local rules FIRST!
The 'walrus operator' could be applied:
>>> x = 5
>>> y = (x := x + 1); x
6
>>> x, y
(6, 6)
However, if such were submitted for Code Review, unhappiness would result.
Was the question re-phrased to: how to ... in Python, we'd end-up with
something more like this:
>>> x = 5 # define
>>> x += 1 # increment
>>> y = x # alias
>>> x, y
(6, 6)
Or, still Pythonic but simpler:
>>> x = 5
>>> y = x = x + 1
>>> x, y
(6, 6)
