Consider the following system of linear equations....

Consider the following system of linear equations. 

\( x _ { 1 } + x _ { 2 } = - 8 \) \(x _ { 2 } - x _ { 3 } = - 2 \) \(x _ { 2 } + x _ { 3 } = - 6\)

Solve the system using the Inverse Matrix Method. What is the inverse \( A ^ { - 1 } \) of the coefficient matrix \( A ? \) 

\( A ^ { - 1 } = - 2 \) 

\( x _ { 3 } = \) 

\( x _ { 2 } = \)
