## Problem 553

Let $T:\R^3 \to \R^3$ be the linear transformation defined by the formula
$T\left(\, \begin{bmatrix} x_1 \\ x_2 \\ x_3 \end{bmatrix} \,\right)=\begin{bmatrix} x_1+3x_2-2x_3 \\ 2x_1+3x_2 \\ x_2-x_3 \end{bmatrix}.$

Determine whether $T$ is an isomorphism and if so find the formula for the inverse linear transformation $T^{-1}$.
