Simplify the block diagram in figure and obtain the closed-loop transfer function. The first attachment is the question and the second attachment is the first step to the simplification of the block diagram.

2. Relevant equations

What i dont understand is how do you get rid off the summing point before the last block and replace it with the block( (1/G2(s))+1) in the first step. I dont understand the first step at all. any help would be appreciated. thanks.
