Given the matrix
\left[\begin{array}{rrr}
-2 & -5 & 1 \\
-1 & 1 & -1 \\
1 & 1 & 0 \\
\end{array}\right],

(a) does the inverse of the matrix exist?

Your answer is (input Yes or No):

(b) if your answer is Yes, write the inverse as\left[\begin{array}{rrr}
a_{11} & a_{12} & a_{13} \\
a_{21} & a_{22} & a_{23} \\
a_{31} & a_{32} & a_{33} \\
\end{array}\right],
