I am an Audacity neophyte and I have what may seem to others to be a basic question. I have recorded 2 sides of an LP album to 2 separate tracks in Audacity (I know there are other ways to do this). I want to edit the second track (album side 2) to remove a little time from the end of it but cannot seem to be able to do it without the editing affecting the same time frame on the first track. Can someone please help me?
Edits apply to tracks that are selected. Click above Mute / Solo in the track you want to edit, then the edit will apply only to that selected track. See: http://manual.audacityteam.org/o/man/audacity_selection.html .

I tried the method you mentioned in your reply as well as a method in the audacity manual you referred me to: double-click inside the track to be edited. I don’t know what I’m doing wrong but neither method works. Both methods cut the same amount of time from both tracks. I may as well just record that track again because I think it will be less time-consuming but I would like to know how to use the software properly.
The click above Mute/Solo selects all the track, just to show you how to do that.
The double-click in the waves selects the entire clip, but if you have not made separate clips, it does the same as click above Mute / Solo and selects all the track.
If you then just drag-select the piece you want to cut at the end of that second track, the delete should only delete that section in that track. If it deletes the same section in the first track, Edit > Undo then choose the Tracks Menu, and click on Sync-Lock Tracks to remove the tick (checkmark) from it. The Sync-Lock must be why the edit is affecting the unselected track.
If the problem is that you drag selected into the upper track as well, hold SHIFT and click above Mute / Solo in the first track to deselect that track, so the small piece to be removed is only selected in the second track.

Unchecking the Sync-Lock enabled me to cut out the section of the second track without changing the first track. IT WORKS!! I know I could have re-recorded and saved some of this back and forth time but I’m happy to learn how to do it right. I’ve had this situation several times before and just re-recorded. Now I’ll save that time. Thanks so much for your help. 
I’m glad you figured it out. 
Sync-Lock Tracks is not on by default but it can be useful if you want to keep the audio tracks synchronised or to keep labels synchronised with the audio they relate to. You may at some stage want to use labels to export multiple files for each song on the album.
For example with Sync-Lock Tracks on, you don’t need to select in the label track as well as the audio track to cut some audio and have the labels to right of the cut move back.
