**bobpursley**, Friday, February 22, 2013 at 7:29pmPlease change your screenname, it is just a little presumptious that somehow you should go to the head of the line.

1/(a-y) or (1/a) - y ?

**JJ**, Friday, February 22, 2013 at 7:33pmIf it is 1/(a-y) = 1/y

then cross multiply to get y = a -y

solve for y in terms of a.

**bobpursley**, Friday, February 22, 2013 at 7:47pmcross multiply is a very dangerous term for beginning students. Change your thinking to

multipy both sides by y then

multiply both sides by a-y

giving

y=a-y

then add y to both sides

2y=a

divide both sides by 2

y=a/2
