If x varies as the square of y and inversely as z
\n" ); document.write( "

\r\n" );
document.write( "Whatever comes after \"varies as\" is multiplied by k and goes on top, \r\n" );
document.write( "and what comes after \"inversely as\" goes on the bottom.\r\n" );

and x=12 when y=3 and z=6,

find x when y=9 and z=6.
