Let $$A=\left(\begin{array}{ccc} 1 & 2 & 0 \cr 1 & 2 & 4 \cr 1 & -2 & 5 \end{array}\right)$$ Find $A^{-1}$ and use it to solve $$AX=B$$ where $$B=\left(\begin{array}{c} 1 \cr 0 \cr -1 \end{array}\right)$$ $$X=\left(\begin{array}{c} x_{1} \cr x_{2} \cr x_{3} \end{array}\right)$$ where $x_{1}=$ , $x_{2}=$ and $x_{3}=$ .
