I'm trying to label a set of functions as a specific number (9.125), like how equations are usually labeled with \begin{equation}
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}
\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}
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 \begin{equation}\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 aminipage
, inside anequation
, which then allows you to use\tag{9.125}
:The
minipage
is actually also set in a zero-width box so that the equation number can overlap with theIEEEeqnarray
block.
