You guys have done a great job of over complicating a rather simple problem (for a 9th grader).

FYI: you're simply wrong here. The only case where that's true is when x = {-1, 0, 1}; for any other value of x, your equality is false.

[ -25/27x = -25/(27x) ] is the valid statement.

I think it's just a syntax thing at this point - and perhaps (-25/27)x is what baddog meant but you're still wrong in what I quoted. No question there.

Math is an international language, and parentheses are everything in math... if your elementary math instructors taught you otherwise, you'd do well to write the givers of your early education a strongly-worded letter.
