Final answer:

To write the system of equations from an augmented matrix, identify each row as an equation and each column as variable coefficients or constants. Convert this into algebraic equations with variables on one side and constants on the other.

Step-by-step explanation:

To write the system of equations associated with an augmented matrix, we begin by determining the system of interest and identifying what information is given in the matrix. Each row in the matrix represents an equation in the system, and each column represents coefficients for a particular variable, with the final column representing the constants after the equals sign.

Since the specific augmented matrix is not provided, we'll explain the process using a generic 2x3 matrix as an example:

For the first row of the matrix [a b | c], the associated equation would be ax + by = c.

For the second row of the matrix [d e | f], the associated equation would be dx + ey = f.

Here, a, b, c, d, e, and f are the numeric coefficients and constants from the matrix, and x and y are the variables. The vertical bar separates the coefficients of the variables from the constants.

Remember to treat equations as sentences expressing important concepts in precise ways. In creating these equations, you are converting the compact, numerical representation of a matrix into a verbal and algebraic form that articulates the relationships between variables in the system.

Solution

- The solution steps are:


\begin{gathered} \begin{bmatrix}{x} & & \\ {y} & & \\ {z} & & {}\end{bmatrix}\begin{bmatrix}{1} & {0} & {0}|6 \\ {0} & {1} & {0}|7 \\ {0} & {0} & {1}|2\end{bmatrix} \\ \\ \begin{bmatrix}{x} & & \\ {y} & & \\ {z} & & {}\end{bmatrix}\begin{bmatrix}{1} & {0} & {0} \\ {0} & {1} & {0} \\ {0} & {0} & {1}\end{bmatrix}=\begin{bmatrix}{x} & {0} & {0} \\ {0} & {y} & {0} \\ {0} & {0} & {z}\end{bmatrix}=\begin{bmatrix}6 & & \\ 7 & & \\ 2 & & {}\end{bmatrix} \\ \\ \text{ This means that:} \\ x+0y+0z=6 \\ 0x+y+0z=7 \\ 0x+0y+z=2 \\ \\ \\ \therefore x=6,y=7,z=2 \end{gathered}
