The image contains a problem in Indonesian that asks to transform a given matrix into the identity matrix using elementary row operations (OBE - Operasi Baris Elementer). The matrices provided are:

1. \[
\begin{pmatrix}
1 & 2 \\
2 & 5 \\
\end{pmatrix}
\]
2. \[
\begin{pmatrix}
1 & 2 & 3 \\
3 & 4 & 1 \\
\end{pmatrix}
\]
3. \[
\begin{pmatrix}
1 & 1 & 1 \\
2 & 3 & 4 \\
1 & 4 & 9 \\
\end{pmatrix}
\]
4. \[
\begin{pmatrix}
1 & 4 & 5 \\
6 & 2 & 3 \\
1 & 7 & 0 \\
\end{pmatrix}
\]

Let's solve one of these matrices to transform it into the identity matrix using elementary row operations. Which matrix would you like to solve? Or do you want to work through all of them?

Ubahlah matriks berikut menjadi matriks identitas dengan OBE: 
(1) [1 2; 2 5], (2) [1 2 3; 3 4 1], (3) [1 1 1; 2 3 4; 1 4 9], (4) [1 4 5; 6 2 3; 1 7 0]

This page guides through the process of transforming several matrices into identity matrices using Elementary Row Operations (OBE). Matrices include 2x2 and 3x3 examples. Learn key concepts of matrix transformation and row reduction techniques.
