I have been learning by playing 'Spark Chess' on line..and anytime my king is being checked by the opposition placing their piece beside my King, can my king capture that threatening piece?
can a king capture an adjacent threatening piece to eliminate a check
yes, unless that piece is protected
'unless that piece is protected'....does that mean I can capture the adjacent threatening piece, as long as another opponent's piece is protecting the threatening piece and could place my king back into check?
In this position, the rook is protected, so you can't take it
Here, the rook isn't protected, so you can take it.

Forgive me if I misunderstand you, but I believe this is the answer to your question...
In this case, you can capture the rook to put your king out of check, because doing so escapes the check and puts you on an unprotected square:
But in this one, you can't, as the piece is protected by the bishop, and capturing the rook would put your king in a second check:

Oops, it looks like @lidasx beat me to it 
Anyways, I hope that helps.
If an opposing piece (ie: Queen) places my king in check with their piece beside my king, can my king capture that piece to prevent the check.
