HELP! How do you undo a SK2P?

So the pattern had me slip two st as if to k2, k1, pass slipped sts over the k st (sk2p).

How on earth do I undo this? I have made a mistake in my pattern and I have to go way back…I am knitting on circular needles I do not know if that will matter.

Thanks!!!

It doesn’t matter if you use circs or straights. When you get to the dec, slip the 2 slip sts back over other st to the R needle, take out the k1 and slip the 2 sts to the L needle.
