Question
Solve the linear system.
![The image displays a system of linear equations with four variables. The system is as follows:
\[
\begin{cases}
3x_1 - 6x_2 + x_3 + 13x_4 = 15 \\
3x_1 - 6x_2 + 3x_3 + 21x_4 = 21 \\
2x_1 - 4x_2 + 5x_3 + 26x_4 = 23
\end{cases}
\]
This system consists of three equations. Each equation is a linear combination of the variables \(x_1\), \(x_2\), \(x_3\), and \(x_4\), set equal to a constant on the right-hand side. The coefficients of the variables are integers.
Understanding such systems of equations is fundamental in linear algebra, and they often arise in various scientific and engineering applications. Solving them typically involves finding the values of the variables that satisfy all of the equations simultaneously. Techniques such as substitution, elimination, or matrix methods can be utilized to solve these systems.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc303f822-5e20-4d30-8920-178170554c96%2Fb456c13c-17d9-4c91-9a94-787a36e234cf%2Fkv5914c_processed.png&w=3840&q=75)
