Multiple Choice

Use Inverses to Solve Matrix Equations
Write the linear system as a matrix equation in the form AX = B, where A is the coefficient matrix and B is the
constant matrix.
- $\left[ \begin{array} { l l l } 2 & 5 & 7 \\ 9 & 0 & 8 \\ 4 & 9 & 0 \end{array} \right] \left[ \begin{array} { l } x \\ y \\ z \end{array} \right] = \left[ \begin{array} { r } - 2 \\ 4 \\ 2 \end{array} \right]$

• A) \(2 x + 5 y + 7 z = - 2\)
• \(9 x + 8 z = 4\)
• \(4 x + 9 y = 2\)
• B) \(2 x - 5 y + 7 z = - 2\)
• \(9 x + 8 z = - 4\)
• \(4 x + 9 y = - 2\)
• C) \(2 x + 5 y + 7 z = - 2\)
• \(9 x + 8 z = 4\)
• \(4 x + 9 z = 2\)
• D) \(2 x + 5 y + 7 z = - 2\)
• \(9 x + 8 y = 4\)
• \(4 x + 9 z = 2\)
