Consider the matrix \( A = \begin{pmatrix} 1 & 2 & -1 \\ 4 & 2 & -2 \\ 4 & 5 & -3 \end{pmatrix} \). Go through the elementary row operation algorithm to determine the inverse of a matrix, and show that \( A \) is not invertible (i.e., singular). Consider the system of equations \[ A \begin{pmatrix} x \\ y \\ z \end{pmatrix} = \begin{pmatrix} a \\ b \\ c \end{pmatrix}. \]What is the relationship between \( a, b, c \) if the system has a solution (i.e., consistent)? Solve the system if it is consistent.HOMEWORK 9What is the relationship between \( a, b, c \) if the system has a solution (i.e., consistent)? Solve the system if it is consistent.
