(a) Let $C = \begin{bmatrix} 1 & 1 & -2 \\ 4 & 5 & -11 \\ -2 & -3 & 8 \end{bmatrix}$. (i) (6 marks) The matrix $C$ is invertible. Compute $C^{-1}$ using the algorithm from this course. Show your work. (ii) (2 marks) Use $C^{-1}$ to solve the following system of linear equations $x_1 + x_2 - 2x_3 = 4$ $4x_1 + 5x_2 - 11x_3 = 9$ $-2x_1 - 3x_2 + 8x_3 = -2$ (b) (6 marks) Suppose that $A$, $B$, and $X$ are invertible square matrices of the same size. Solve for $X$ in terms of $A$ and $B$ and simplify your result as much as possible. Show your work. $(4B^{-1}X)^{-1} = ((3A)^{-1}B)^{-1}BA^3$
