Do you have any suggestion how to make such formula? Or maybe I need to draw them somehow?
Big thanks for any hints!

I suggest using nicematrix.
\documentclass{article} \usepackage{nicematrix, tikz} \begin{document} \[ \begin{pNiceArray}{rrrrr}[first-row] \downarrow && \downarrow && \downarrow\\ 1 & 3 & 3 & 2 & 1\\ 2 & 6 & 9 & 5 & 2\\ -1 & -3 & 3 & 0 & 1\\ 3 & 9 & 6 & 5 & 2 \end{pNiceArray} \sim \begin{pNiceArray}{rrrrr}[first-row] \downarrow && \downarrow && \downarrow\\ 1 & 3 & 3 & 2 & 1\\ 0 & 0 & 3 & 1 & 0\\ 0 & 0 & 0 & 0 & 2\\ 0 & 0 & 0 & 0 & 0 \CodeAfter \tikz \draw (2-|1)--(2-|3)--(3-|3)--(3-|5)--(4-|5)--(4-|6); \end{pNiceArray} \] \end{document} If you want to tighten up the spacing in the first matrix, you can change the first line to \begin{pNiceArray}{@{\,}r@{\;}rrrr}[first-row]
