When ice melts it takes up 92% of its original volume as water. Let x% of Earth's total floating icecap volume be above water, and let y% be below water. Earth's floating icecap volume is z% of Earth's total icecap volume. If z>0, by what percent must y decrease in terms of x and z so that no change occurs if Earth's icecaps melt?

I don't know, but maybe you should rethink this question. Because ice that is floating on the seas does not change the sea level when it melts - ice cubes floating in a glass of water, for example, do not change the level of water in the glass by melting, even when some parts of the cubes are above the water line. Thus, only the ice that is NOT floating on the seas, when it melts and flows into the sea, changes the sea level.

Like another poster said, floating ice will not make a difference to sea levels whether it melts or not. Only land ice melting will cause sea levels to rise. So I think the answer is probably simple (trick question) -- Y must decrease the same percent as X and Z. In other words, the part under water for floating ice will always be same proportion to the amount above water and also to total floaing ice.

Are you talking #1, 2, 3, or 4 ice.
