嗨，我是 Latex 新手，需要帮助整理我的方程式。这是我有的。
- 我需要方程（3）与数字（3）对齐
- 方程 (5) 和 (6) 仅彼此居中且对齐
这是 mwe。https://www.overleaf.com/latex/templates/icml-2019-submission-template/vkqjjvzjvhdc

\documentclass{article}
% Recommended, but optional, packages for figures and better typesetting:
\usepackage{microtype}
\usepackage{graphicx}
\usepackage{subfigure}
\usepackage{booktabs} % for professional tables
\usepackage{amsmath}
% hyperref makes hyperlinks in the resulting PDF.
% If your build breaks (sometimes temporarily if a hyperlink spans a page)
% please comment out the following usepackage line and replace
% \usepackage{icml2019} with \usepackage[nohyperref]{icml2019} above.
\usepackage{hyperref}
% Attempt to make hyperref and algorithmic work together better:
\newcommand{\theHalgorithm}{\arabic{algorithm}}
% Use the following line for the initial blind version submitted for review:
\usepackage{icml2019}
% If accepted, instead use the following line for the camera-ready submission:
%\usepackage[accepted]{icml2019}
% The \icmltitle you define below is probably too long as a header.
% Therefore, a short form for the running title is supplied here:

% It is OKAY to include author information, even for blind
% submissions: the style file will automatically remove it for you
% unless you've provided the [accepted] option to the icml2019
% package.
% List of affiliations: The first argument should be a (short)
% identifier you will use later to specify author affiliations
% Academic affiliations should list Department, University, City, Region, Country
% Industry affiliations should list Company, City, Region, Country
% You can specify symbols, otherwise they are numbered in order.
% Ideally, you should not use this facility. Affiliations will be numbered
% in order of appearance and this is the preferred way.

\begin{abstract}
This document provides a basic paper template and submission guidelines.
Abstracts must be a single paragraph, ideally between 4--6 sentences long.
Gross violations will trigger corrections at the camera-ready phase.

编辑：感谢 leandriis 的回答。但为什么 overleaf 会突出显示所有内容，好像这是错误一样？当我将 align 嵌套在 gather 中时，就会发生这种情况
答案1
结合您之前三个问题的评论和答案，我最终得到了以下 MWE。在其中，我在一个环境align中使用了两个环境，gather正如我之前推荐的那样。对于第一个变体，我保留了\small字体大小和\hspace*命令，而在第二个示例中，我将第三个方程拆分为两行，以防止方程编号向下移动。这是已由 Mico 推荐。

答案2
我也会在环境align中使用一对环境gather。我会不是不过，请使用。为了使所有六个方程式都符合，我将重置、和\hspace*{-0.2cm}的值。这些参数控制在数学运算符两侧插入的空格量。thinmuskip\medmuskip\thickmuskip
哦，我不会写||，即两个连续的|符号来创建“标准”分隔符。相反，使用\lVert和\rVert或者更优雅地加载包并创建带有可变大小围栏mathtools的宏。\norm
