The matrix on the right results after performing a single row operation on the matrix on the left. [2 3 27 [2 -1 -3 87 row op produces: 4 -3] 4 -1 -2 -1 5 -2 2 4 4 -3] Identify the row operation. Use R1, R2, and R3 to represent the rows R1, R2, and R3. For example, if the operation were "add 2 times row 4 to row 6" then the answer would be "2 * R4 + R6 → R6". If it were "swap row 4 with row 6" the answer would be "R4 → R6". Answer: select

Identify the row operation. Use R1, R2, and R3 to represent the rows R1, R2, and R3. For example, if
the operation were "add 2 times row 4 to row 6" then the answer would be "2 * R4 + R6 → R6". If
it were "swap row 4 with row 6" the answer would be "R4 < → R6".
