So i have a question about where the wedges and ladders would end up at the end of the attached picture. I can't figure it out and would like someone to explain it to me.
Thanks.

This doesn't show the other side of the compound. It only shows the O- wedge. I need to know where the other wedge would go on an open chain and not a ring.

Just read accompanying text in point 2.

Ok thank you, I understand the inversion now. One last thing though, in the example I gave, would the CH3 on the right side or the H on the right side be on the wedge?

The right picture lost stereochemistry, but from the middle one, you can set it correctly. This is as simple as the SN2 mechanism.
