Please explain the meaning of the encircled item on the first picture, and please also explain how did you come up on the final answer (2nd picture)

Step 2 The density of W is as follows: F (y) = P(Y<y) = P(2-x< y) = P(x22-y) =1-P(x<2-y) =1-F(2-y) f (y)=(1-F (2-y)) dy =-f (2-y)x-1 = f (2- y) = (2- y) 1<y<3 2 -
