# Customizing Equation-Numbering / Labeling in IEEEeqnarray

I'm trying to label a set of functions as a specific number (9.125), like how equations are usually labeled with or \begin{IEEEeqnarray}. I have been using \tag{} (with a customized number like 9.034 inside the \tag, so each equation is individually labeled with my own choice of text/writing) for most of my document and I don't want to have to change all those again just so I can get this one section right (40 page document!).

This is what I want to be labeled (9.125):

\begin{IEEEeqnarray}{LR}
\end{IEEEeqnarray}


I know commands like \IEEEyesnumber and I'm aware of people changing the labels of subsections and what not inside IEEEeqnarray. I just want to give this equation (no sub-equations or etc) a customizable label, where it functions the same way as \tag. I don't even want to "reference" it like a label throughout the text, that's not even necessary, I just want the number 9.125 in brackets to appear to the side exactly like it would in \tag{9.125}. How can I accomplish this?

If it is of any use, which I don't think it should be, my preamble is as follows:

\documentclass[12pt]{article}
\usepackage{IEEEtrantools}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{amsfonts}
\usepackage[pdftex]{graphicx}
\usepackage[width=16.00cm, height=22.00cm]{geometry}


Any help would be appreciated!

Here I've set the entire IEEEeqnarray structure inside a minipage, inside an equation, which then allows you to use \tag{9.125}:

\documentclass{article}
\usepackage{IEEEtrantools}% http://ctan.org/pkg/ieeetran
\usepackage{amsmath}% http://ctan.org/pkg/amsmath
\usepackage[width=16.00cm, height=22.00cm]{geometry}% http://ctan.org/pkg/geometry
\begin{document}
\begin{IEEEeqnarray}{LR}
$$\makebox[0pt]{\begin{minipage}{\linewidth} \begin{IEEEeqnarray*}{LR} \frac{a}{b}+\frac{c}{d}=0,\qquad&\qquad\frac{e}{f}-\frac{g}{h}=0 \\[10pt] \frac{i}{j}+\frac{k}{l}=0,\qquad&\qquad\frac{m}{n}+\frac{o}{p}=0 \end{IEEEeqnarray*} \end{minipage}} \tag{9.125}$$

The minipage is actually also set in a zero-width box so that the equation number can overlap with the IEEEeqnarray block.
