I just answered this a few minutes ago. Notice what question is asked! \r
\n" ); document.write( "\n" ); document.write( "You do not need to try to solve for both x and y.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Two numbers, x and y.
\n" ); document.write( "\"x%5E2%2By%5E2=256\" and \"%28x%2By%29%5E2=784\".
\n" ); document.write( "The second equation is \"x%5E2%2B2xy%2By%5E2=784\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract the circle equation from the second equation:
\n" ); document.write( "\"x%5E2%2B2xy%2By%5E2-x%5E2-y%5E2=784-256\"
\n" ); document.write( "\"2xy=528\"
\n" ); document.write( "\"highlight%28xy=264%29\", the answer.
\n" ); document.write( "
\n" );
