Help!!!! Is this rubix configuration solvable? These are the only two pieces in the wrong place.
If the answer is no, what pieces do I need to reconfig to make the cube solvable? Note that my kid may have accidentally flipped the corner piece or swapped a center while playing with the cube.
It is not possible to swap a single pair of edges by doing legal cube moves.
The simplest way to fix it is, well, to fix it: take it apart enough that you can bodily swap the two edge pieces back again.
