Find the Row Reduced Echelon Form (RREF).
![The image contains two matrices, labeled 15 and 16.
Matrix 15 is a 3x4 matrix:
\[
\begin{bmatrix}
2 & 2 & 4 & 2 \\
1 & -1 & -4 & 3 \\
2 & 7 & 19 & -3 \\
\end{bmatrix}
\]
Matrix 16 is also a 3x4 matrix:
\[
\begin{bmatrix}
1 & 3 & 15 & 7 \\
2 & 4 & 22 & 8 \\
2 & 7 & 34 & 17 \\
\end{bmatrix}
\]
These matrices could be used in educational contexts to illustrate operations such as addition, subtraction, or multiplication of matrices. Each matrix has three rows and four columns, which can be further used to explain how matrix dimensions affect the ability to perform arithmetic operations with other matrices.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc303f822-5e20-4d30-8920-178170554c96%2F07337b2f-1bb1-4c28-943c-1e388df48c7e%2F9imz2th_processed.png&w=3840&q=75)
