You can put this solution on YOUR website!
$\"Z=ktw\"$
\n" ); document.write( " $\"60=k%282%29%2815%29\"$
\n" ); document.write( " $\"k=60%2F30\"$
\n" ); document.write( " $\"k=2\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"Z=2tw\"$
\n" ); document.write( "Now that you know k you can solve,
\n" ); document.write( " $\"Z=2%288%29%289%29\"$
