Chapter 5 - Section 5.2 - Matrix Solution of Linear Systems - 5.2 Exercises - Page 499: 5

Answer

\[ \left[ \begin{array}{cc|c} 2 & 3 & 11 \\ 1 & 2 & 8 \end{array} \right] \]

Work Step by Step

We transform the given equations into $2 \times 3$ matrix such that the coefficients of the variables are on the left-hand side and the constants on the right-hand side of the vertical bar. Therefore, we write the $2 \times 3$ matrix as follows: \[ \left[ \begin{array}{cc|c} 2 & 3 & 11 \\ 1 & 2 & 8 \end{array} \right] \]
