The matrix on the right results after performing a single row operation on the matrix on the left.

$$\left[\begin{array}{rrrr} -3 & 1 & -3 & 3 \\ 5 & 0 & 2 & -1\end{array}\right] \text{ row op produces: } \left[\begin{array}{rrrr} -3 & 1 & -3 & 3 \\ 14 & -3 & 11 & -10\end{array}\right]$$

Identify the row operation. Use R1 and R2 to represent the rows $R_1$ and $R_2$. For example, if the operation were "add 2 times row 4 to row 6" then the answer would be "$2*R4+R6 \longrightarrow R6$". If it were "swap row 4 with row 6" the answer would be "$R4 \longleftrightarrow R6$".
