I am having some difficulties with solving this block diagram. It is required that the node 1 goes at point 2 and the block S moves out of the feedback loop (to 3 and 4). Can anyone help me and draw the next equivalent block diagrams. What should I do, what will happen when I move the node 1 at the point 2?

 

I tried to solve this problem but I am not sure if this is correct! Any kind of information will be of great help Thanks in advance!
