\begin{align}
E_1&=A+B \label{eq:1}\\
\begin{split}
E_2&=(C-D)E_1 \label{eq:2}\\
&\quad +[(1-R)+R(1-Y)\\
&\quad +\pi(1-\delta)]E_2\\
&\quad +F\cdot E_3
\end{split}\\
E_3 &=(\pi\cdot \chi)-(R\cdot E_1)-(RY\delta\cdot E_2) \label{eq:3}
\end{align
}
看起来像：
然后我想要一个单独的方程网格，从这个方程网格继续下去，改编自这个答案。
但是，由于这些是图形的子图部分，因此它们全部的集合目前都进入了我的图形列表，而不是每个都单独进入我的方程式列表。
我仍然想保留方程组的图形标题（进入我的图表列表），但希望子图内的每个标题都出现在我的方程列表中，并进行编号，例如将每个成本函数标记为(8.5)、(8.6)等(8.7)。
接下来的当前代码：
\begin{figure}

\begin{subfigure}[b]{.45\linewidth}
\centering
$$C_cip = {V_cp - V_ci}$$
\caption{VD}\label{fig:cost1}
\end{subfigure}
\begin{subfigure}[b]{.45\linewidth}
\centering
$$C_cip = {|V_cp - V_ci|}$$
\caption{AVD}\label{fig:cost2}
\end{subfigure}
\begin{subfigure}[b]{.45\linewidth}
\centering
$$C_cip = \frac{V_cp - V_ci}{V_ci}$$

此外，我不确定为什么我的标题出现在每个方程的最左侧而不是正下方。有关完整信息，以下是我之前加载的一组包和设置begin{document}：
