How to create numbering in this way: (A), (B), (B.1), (B.2) etc. with \enumerate ?

Thanks for any advice.

(edited in from comment:)

\begin{subequations}
 \renewcommand{\theequation}{\theparentequation.\Alph{equation}}
 \begin{align}
  y & = d \\ y & = cx+d \\
  y & = bx^{2}+cx+d \\ y & = ax^{3}+bx^{2}+cx+d
 \end{align}
\end{subequations}

More details on the context would be helpful. Do you want to redefine numbering of all equations in a document, or a certain type of equations? – Bernard Jun 26 '16 at 10:37
I want to redefine a certain type of equations. – Pls2 Jun 26 '16 at 10:39
And they need their own counter (for the numeric part)? – Bernard Jun 26 '16 at 10:42
Yes, they need their own counter. – Pls2 Jun 26 '16 at 10:43
The answers to how-to-create-new-counter-of-equation seem to solve your problem. – Bernard Jun 26 '16 at 10:57
A warm welcome to TeX.SE! Although it seems that @Bernard has pointed in the right direction you might want to post a MWE http://meta.tex.stackexchange.com/questions/3343/what-makes-a-good-mwe – A Feldman Jun 26 '16 at 11:02
I've tried code that was in how-to-create-new-counter-of-equation , but did't work well – Pls2 Jun 26 '16 at 11:20

Post what you tried, that we can play with… – Bernard Jun 26 '16 at 11:31

i edited in your example from the comment, but we really need more. please make this compilable, with \documentclass, amsmath package if needed, and \begin ... \end{document}. you are always able to edit your own question. – barbara beeton Jun 26 '16 at 15:52
I don't see an enumerate in there! – Jun 26 '16 at 15:56
