\n" ); document.write( "The reason is that you show both \"y\" and \"Y\" in the first expression, and different symbols represent different values. It is not at all uncommon to use, for example, r and R to represent the radii of two circles.

\n" ); document.write( "So in this problem (as you post it) you can't simplify \"-2y+Y\" to \"-y\".

\n" ); document.write( "The lesson for you: don't mix lower- and upper-case letters to represent the same number.
