You can put this solution on YOUR website!
  • \"%28-1%29%2F%28-1%29+=+1\"
  • Multiply one of your fractions by -1/-1 (since this is a 1, we are not really changing anything other than the appearance).
  • If the multiplied fraction works out the same as the other fraction, then they are, and were, the same!

\n" ); document.write( "What you posted actually meant:
\n" ); document.write( "\"3x-2%2F1-x\" and \"-3x%2B2%2F-1%2Bx\"
