convert matrix to system

Post by vinc »

Hello

I would like to display with LaTeX the start of calculation below

Image

Code: Select all

A.X=0 \Longleftrightarrow

\[M(A)=\left(
  \begin{array}{*{2}{c}}
  
  4&-2\\
  5&-3\\
  


\left(
 \begin{array}{*{1}{c}}
 
 X\\
 Y

\end{array} \right)\] =0 \Longleftrightarrow

\begin{cases}

4x-2y=0\\
6x-2y=0\\

\end{cases}


Could you help me solve this little problem.

Thank you!

See you soon

I tried to do. It caused a lot of bugs, I think the mix of text and number and tag issues.

You could use pmatrix instead of array:

Code: Select all

\documentclass{article}
\usepackage{mathtools}% loads amsmath

\begin{document}
\[
    AX=0 \Longleftrightarrow
    \begin{pmatrix}
    4&-2\\
    5&-3
    \end{pmatrix}
    \begin{pmatrix}
    X\\
    Y
    \end{pmatrix}
    =0 \Longleftrightarrow
    \begin{cases}
    4x-2y=0\\
    6x-2y=0
    \end{cases}
\]
\end{document}
Your source code makes me suspect that you have not yet read a LaTeX introduction. Please catch up.

We do not know the example that generates these error messages.
