A single row operation was performed on the matrix on the left to produce the matrix on the right. Unfortunately, an error was made when performing the row operation. -2 1 -4 -20 -8 row op produces: 1 17 -3 0 -4 |-3 0 -4 4 First identify the row operation, then fix the error. Use R1, and R2 to represent the rows R1, R2. 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".
