\n" );
document.write( "Let x represent the days it takes together
\n" );
document.write( "Amount done per day is the Equalizer
\n" );
document.write( "1/4 + 1/6 + 1/2 = 1/x 
\n" );
document.write( "Mulitplying both sides of the equation by 12x so as all denominators = 1
\n" );
document.write( "3x + 2x + 6x = 12
\n" );
document.write( "11x = 12
\n" );
document.write( "x = 12/11
\n" );
document.write( "x = 1.09 hrs \n" );
document.write( "
