Nice concerted effort for the easier problem (all squares allowed to be differently sized). Only one case can be improved I think.

solving abstract problems is like sex: it may occasionally have some practical use, but that is not why we do it.
xy - y = x5 - y4 - y3 = 20; x>0, y>0.

duh, yeah.. 7 = 3+4
Cut the square in 4, then cut one of the smaller squares in 4 again.
