Question
![**Title: Solving a System of Equations Using the Inverse of a Coefficient Matrix**
**Objective:**
Learn how to use the inverse of the coefficient matrix to solve a system of linear equations.
**System of Equations:**
1. \( x + 2y + 3z = 20 \)
2. \( 2x + 3y + 4z = 3 \)
3. \( -x - 2y - 2z = -31 \)
**Task:**
Use the inverse of the coefficient matrix to find the values of \(x\), \(y\), and \(z\).
**Answer Format:**
\[(x, y, z) = \left(\begin{array}{c} \_\_ \\, \_\_ \\, \_\_ \end{array}\right)\]
