### System of Linear Equations
Consider the following system of linear equations:
1. \( 2x_1 + 4x_2 + 4x_3 + 2x_4 = 16 \)
2. \( 4x_1 + 8x_2 + 6x_3 + 8x_4 = 32 \)
3. \( 14x_1 + 29x_2 + 32x_3 + 16x_4 = 112 \)
4. \( 10x_1 + 17x_2 + 10x_3 + 2x_4 = 28 \)
This system consists of four equations with four variables: \(x_1\), \(x_2\), \(x_3\), and \(x_4\). Each equation represents a linear relationship among these variables.
To solve for the values of these variables, one may use various methods such as substitution, elimination, or matrix operations including Gaussian elimination or using inverse matrices if applicable.
Understanding such systems is fundamental in linear algebra and has numerous applications in fields such as engineering, economics, and physics.
