QuestionWrite the system of equations as a matrix equation $A X=B$, with $A$ as the coefficient matrix of the system. $$\begin{array}{rr} x-2 y+4 z= & -8 \\ 2 x+6 y-5 z= & 4 \\ 2 x-6 y+6 z= & 2 \end{array}$$

Studdy Solution
The matrix equation representing the given system of equations is: $$\begin{bmatrix} 1 & -2 & 4 \\ 2 & 6 & -5 \\ 2 & -6 & 6 \end{bmatrix} \begin{bmatrix} x \\ y \\ z \end{bmatrix} = \begin{bmatrix} -8 \\ 4 \\ 2 \end{bmatrix}$$
