Let the distance traveled by the eastbound car = $\"d\"$ mi
\n" ); document.write( "given:
\n" ); document.write( " $\"18%5E2+%2B+d%5E2+=+%28d+%2B+6%29%5E2\"$
\n" ); document.write( "---------------------------
\n" ); document.write( " $\"324+%2B+d%5E2+=+d%5E2+%2B+12d+%2B+36\"$
\n" ); document.write( "Subtract $\"d%5E2\"$ from both sides
\n" ); document.write( " $\"324+=+12d+%2B+36\"$
\n" ); document.write( " $\"12d+=+288\"$
\n" ); document.write( " $\"d+=+24\"$
\n" ); document.write( "The eastbound car traveled 24 mi \n" ); document.write( "

\n" );
