1/ay=1/y
solve for "y"

Please change your screenname, it is just a little presumptious that somehow you should go to the head of the line.
is the left side
1/(ay) or (1/a)  y ? 
If it is 1/(ay) = 1/y
then cross multiply to get y = a y
solve for y in terms of a. 
cross multiply is a very dangerous term for beginning students. Change your thinking to
multipy both sides by y then
multiply both sides by ay
giving
y=ay
then add y to both sides
2y=a
divide both sides by 2
y=a/2
