Use Technology to Solve the System of Equations $\begin{array} { l } 1.6 x + 2.4 y - 3.2 z = 17.6 \\5.1 x - 6.3 y + 0.6 z = - 12.8 \\4.2 x + 3.5 y + 4.9 z = 40.4\end{array}$

Use technology to solve the system of equations. Express all solutions as decimals, rounded to one decimal place.
$\begin{array} { l } 1.6 x + 2.4 y - 3.2 z = 17.6 \\5.1 x - 6.3 y + 0.6 z = - 12.8 \\4.2 x + 3.5 y + 4.9 z = 40.4\end{array}$
