添加另一个与问题本身超链接的答案

Question

我在这里问了这个问题 将答案与解决方案区分开来的最佳方法是什么？ 并得到了很好的答案。虽然我现在遇到了一个新问题。

我想输入问题，然后让一个答案链接到数字。另一个答案链接到问题本身。（请参阅我在 Inked 线程中的 MWE 作为示例。单击问题旁边的数字应该会将您发送到一个位置，单击等式本身应该会将您发送到其他地方）

以下是我迄今为止取得的进展的 MWE

因此，我想在每个问题下面添加另一个答案，例如下面这样

\begin{IntList}{3}
    \begin{question}
        $\displaystyle \int\sqrt{4-x}\dx$
            \begin{mysolution}
                $2+3+4$
            \end{mysolution}
             \begin{myanswer}
                To solve this problem one must first...
            \end{mysanswer}
    \end{question}
\end{IntList}

我的答案与整个问题相关联，而解决方案与数字相关联。最好链接方程的工作方式与答案相同。例如，超链接双向工作。有什么想法吗？

编辑：这是一个更简单的例子

\documentclass[10pt,a4paper]{article}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{amsmath}

\usepackage{enumitem}
\usepackage{multicol}
\usepackage{mathtools}

\newenvironment{IntList}[1]{%
\centering
\setlength{\columnsep}{50pt}
\begin{multicols}{#1}\begin{enumerate}[itemsep=5pt]}{\end{enumerate}\end{multicols}}

\usepackage[hidelinks]{hyperref}
\newcommand{\IntExerc}[2]{\item \hyperref[#1]{\mbox{ \( \displaystyle #2 \) }}}

\begin{document}

\begin{IntList}{3}
\IntExerc{R1.1}{\int \frac{x^2+3x}{x^2} \,\mathrm{d}x}
\IntExerc{R1.22}{\int\sin(x)\,\mathrm{d}x}
\IntExerc{R1.2}{\int_0^1 \frac{x}{x^2+1} \,\mathrm{d}x}
\end{IntList}

\newpage

\newpage

\begin{align}
\int \frac{x^2+3x}{x^2} \, \mathrm{d}x & = \int \frac{x^2}{x^2} + \frac{3x}{x^2} \, \mathrm{d}x = \int 1 \mathrm{d}x + 3\int \frac{\mathrm{d}x}{x} = x + 3 \ln|x| + \mathcal{C}  \label{R1.1} \\
\int\sin(x)\,\mathrm{d}x & = -\cos(x) + C \label{R1.22} \\
\int\sin(x)\,\mathrm{d}x & = -\cos(x) + C \label{R1.2}
\end{align}

\end{document}

这更接近我想要的答案包的输出。请注意，我必须单独输入答案，添加标签。并且没有附加到数字的超链接。

（我也希望有下面的语法，但我想这是不可能的。）

\begin{Questions}[PartI]
\question
\solution
\answer

\question
\solution
\answer
\end{Questions}

\display{solution}{PartI}

\display{answer}{PartI}

现在，任何评论和帮助都将非常有用。

Answer 1

所以听起来你既想要shortsolution环境又longsolution想要环境。这里有一个解决方案可以做到这一点 - 它与我之前对你的问题的解决方案非常相似，希望它令人满意，如果不满意请告诉我。

我对链接进行了颜色编码，以便

• 红色链接指向shortsolutions
• 蓝色链接转到longsolutions

随着问题更新，特别是是否可以在开头就给出答案？

是的，这是可能的，但请记住，您的解决方案文件（shortsolutions.tex和longsolutions.tex）已更新每次编译时。如果您在开始文档的，你实际上看到的是它们的先前版本 - 这就是为什么当你将它们包含在结尾您的文档。

下面是一个 MWE，演示了它的工作原理 - 请注意，你需要编译两次编辑任何解决方案后。
