I cannot put an equation and figure inside same frame on beamer

Question

I have a very basic question. I am trying to use beamer to prepare a presentation and I need to put a figure and 2 line equation one under the other. I am able to put figure by itself but when I add the equation, I cannot see it on the output. I am using overleaf. I share the code I used in that frame below. The figure was an svg and I converted it to proper version as suggested here.

Code:

\begin{frame}[fragile]{ Recurrent Neural Networks(RNNs)}
\begin{figure}
    \centering
    \def\svgwidth{\columnwidth}
    \input{rnn.pdf_tex}
    \caption{Recurrent Neural Network unfolded in time}
\end{figure}
\begin{eqnarray}\label{rnn-eq}
  h_{t} &=& f(W_{hx}x_{t} + W_{hh}h_{t-1} + b) \\
  y_{t} &=& g(W_{yh}h_{t} + c) 
\end{eqnarray}
\end{frame}

Current output:

I am trying to achive something like that:

apparently your image is to high that in frame would have space image and equation. since your image is relatively simple i redraw it by use of the packagetikz:

\documentclass{beamer}
\usepackage{amsmath}
\usepackage{tikz}
\usetikzlibrary{chains,
                positioning,}

\begin{document}
\begin{frame}[fragile]{ Recurrent Neural Networks (RNNs)}
\begin{figure}
    \centering
\begin{tikzpicture}[
node distance = 6mm and 8mm,
  start chain = A going right,
   box/.style = {draw, rounded corners,
                 minimum size=8mm, outer sep=0pt},
  circ/.style = {circle, draw, dashed,
                 minimum size=10mm, inner sep=1pt, outer sep=0pt},
                    ]
\foreach \i/\j/\k [count=\n] in {h_{t-1}/y_{t-1}/x_{t-1}, h_{t}/y_{t}/x_{t}, h_{t+1}/y_{t+1}/x_{t+1}}
{
  \node[circ,on chain=A,join=by -stealth]    {$\i$};
  \node[box, above=of A-\n] (y\n)           {$\j$};
  \node[box, below=of A-\n] (x\n)           {$\k$};
  \draw[-stealth] (A-\n) -- (y\n);
  \draw[-stealth] (A-\n) -- (x\n);
}
  \node[circ, left =of A-1]  (A-0) {$h_{({\dots})}$};
  \node[circ, right=of A-3]  (A-4) {$h_{({\dots})}$};
%
  \draw[-stealth,dashed] (A-0) -- (A-1);
  \draw[-stealth,dashed] (A-3) -- (A-4);
\end{tikzpicture}
    \caption{Recurrent Neural Network unfolded in time}
\end{figure}
\begin{align}\label{rnn-eq}
  h_{t} & = f(W_{hx}x_{t} + W_{hh}h_{t-1} + b) \\
  y_{t} & = g(W_{yh}h_{t} + c)
\end{align}
\end{frame}
\end{document}

in case, that you have image as pdf files, than the simplest way to include them as follows:

\begin{figure}
    \centering
\include graphics[height=4cm]{rnn} % adjust height so, that image and equation will fit in one frame
    \caption{Recurrent Neural Network unfolded in time}
\end{figure}
