im asked to find vx the way it was solved is that a node A was taken just before the op amp and nodal analysis aka kcl was applied and the node after it was called v0. but how did we name the first one A and the 2nd one v0? on what basis? also if im asked to get vx how do i think of taking the node A to get an equation so i can get Vx? what should i look for? im really bad at knowing what nodes to take and apply kcl or nodal analysis on to reach my desired solution so can you please help me with that? at the end of the answer it said vx=v0.2R / R+2R getting -2rA0 please can you address all my points so i can understand what and how to look for when solving this type of question?

Step by step
Solved in 3 steps with 3 images
first off solution is completely incorrect. the correct answer is -2vRA0 and as i said DO NOT RE-SOVLE THE QUESTION BUT JUST ANSWER THE INQUIRIES I HAVE IN THE DESCRIPTION OF THE QUESTION.
