Find a basis of the row space of the matrix $$A = \left[\begin{array}{ccccc} 0 &0 &0 &0 &1\cr -3 &1 &3 &0 &2\cr -3 &1 &3 &0 &1\cr 0 &-3 &4 &-3 &-1 \end{array}\right].$$
Basis:

$\big\lbrace$ $\left[\Rule{0pt}{1.2em}{0pt}\right.$$\left]\Rule{0pt}{1.2em}{0pt}\right.$,
$\left[\Rule{0pt}{1.2em}{0pt}\right.$$\left]\Rule{0pt}{1.2em}{0pt}\right.$,
$\left[\Rule{0pt}{1.2em}{0pt}\right.$$\left]\Rule{0pt}{1.2em}{0pt}\right.$ $\big\rbrace.$
