Write the system in the form $\mathbf{A} \mathbf{X}=\mathbf{B}$. Use $\mathbf{X}=\mathbf{A}^{-1} \mathbf{B}$ to solve the system for each matrix $\mathbf{B}$. $$ \begin{aligned} x_{1}+2 x_{2}+5 x_{3} &=b_{1} \\ 2 x_{1}+3 x_{2}+8 x_{3} &=b_{2} \\ -x_{1}+x_{2}+2 x_{3} &=b_{3} \\ \mathbf{B}=\left(\begin{array}{r} -1 \\ 4 \\ 6 \end{array}\right), \quad \mathbf{B} &=\left(\begin{array}{l} 3 \\ 3 \\ 3 \end{array}\right), & \mathbf{B}=\left(\begin{array}{r} 0 \\ -5 \\ 4 \end{array}\right) \end{aligned} $$
