1.	If A=⎡⎢⎣2−3532−411−2⎤⎥⎦, find A−1. Using A−1 solve the system of equations 2x−3y+5z=11,3x+2y−4z=−5,x+y−2z=−3
Answer» If $A = ⎡ ⎢ ⎣ \begin{matrix} 2 & - 3 & 5 3 & 2 & - 4 1 & 1 & - 2 \end{matrix} ⎤ ⎥ ⎦$ , find $A^{- 1}$ . Using $A^{- 1}$ solve the system of equations $2 x - 3 y + 5 z = 11, 3 x + 2 y - 4 z = - 5, x + y - 2 z = - 3$
