making a single equation larger inside \begin{align} … \end{align}

Question

Hello you wonderful TeX friends!

I have an issue making a single equation that bigger.

I'm restricted to use the align environment for my equations. I've used this answer to make inline math bigger, and I looked at this, but it's as the align environment is a bit tricky here. I would however like to stick to that. Any help or suggestions would be greatly appreciated.

code,

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{align}
2+2 = 4 \\
2=3 = 5 % I only want to make this single line bigger
\end{align}

% I'm aware I can something like this,

\begin{align}
2+2 = 4 
\end{align}
\vspace{-15mm}
{\LARGE 
\begin{align}
2+3 = 5 
\end{align}
}

% but that enlarges the equation number, 
% and I don't want that, along withing
%  adding \end{align} … \begin{align}

\end{document}

Answer 1

Although the example code uses align there are no alignment points specified, which means that you can use a simpler setup such as gather

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{gather}
2+2 = 4 \\
 % I only want to make this single line bigger
\mbox{\LARGE$\displaystyle2=3 = 5$}
\end{gather}

\end{document}
