Find the rank and the nullity of the matrix \[ \begin{array}{l} \quad A=\left[\begin{array}{ccccc} 2 & -4 & -6 & 4 & -7 \\ 1 & -2 & -4 & 1 & -4 \\ 1 & -2 & -3 & 2 & -3 \end{array}\right] \\ \operatorname{rank}(A)= \\ \operatorname{nullity}(A)= \\ \operatorname{rank}(A)+\text { nullity }(A)= \\ \text { Note: You can earn partial cr the number of columns of A } \\ \text { the number of rows of A } \end{array} \]
