You can put this solution on YOUR website!
Do you mean 1%2F%289y%29+=+20 or %281%2F9%29y=+20

In either case, use the formula that says a%2Fb=c%2Fd means ad+=+bc

If you meant, 1%2F%289y%29+=+20 1%2F%289y%29+=+20%2F1
then you have 180y = 1, so y+=+1%2F180

If you meant, %281%2F9%29y=+20,
then you have y%2F9=20%2F1, which gives you y+=+180.

It all depends upon where you meant to put the y!
