The system of the matrix which represents the linear equations are 2x + y + z = 4, 3x - 2y + z = 8, and x - y + z = 5.
What is a matrix?
A matrix is a collection of numbers arranged in rows and columns and enclosed on both sides by square brackets.
The matrix below represents a system of equations.
[tex]\begin{bmatrix}2 &1 &1 &4 \\\\-3 &2 &-1 &-8 \\\\1 &-1 &1 &5\end{bmatrix}[/tex]
The matrix is the linear system of the matrix. And the number of the variable is equal to the number of columns minus one.
The linear systems are given below.
[tex]\begin{aligned} \rm 2x + y + z &= 4\\\\\rm -3x + 2y -z &= -8\\\\\rm x - y + z &= 5\end{aligned}[/tex]
