The augmented matrix below can be reduced to row-echelon form with a single row operation (where we do not require leading entries to be 1 for REF). 1 2 3 0-2 2 0 5-7 | 4 4 12 Complete the description of this row operation: Replace Row with X Row + Row Carry out the indicated row operation, then solve the resulting system by backward substitution. Give the solution vector in exact form with fractions as necessary (do not enter as decimals).
