Write the system $$\left\lbrace \begin{array}{r@{}r@{}r@{}r@{}r} & 10 y & - 6 z & = & 3 \\ 4 x & - 2 y & & = & 11 \\ -3 x & + 9 y & - 7 z & = & 2 \end{array} \right.$$ in matrix form.

$\left[\Rule{0pt}{3.6em}{0pt}\right.$$\left]\Rule{0pt}{3.6em}{0pt}\right.$ $\displaystyle \left\lbrack \begin{array}{c} x \\ y \\ z \end{array} \right\rbrack =$ $\left[\Rule{0pt}{3.6em}{0pt}\right.$$\left]\Rule{0pt}{3.6em}{0pt}\right.$.
