\n" );
document.write( "Hi,
\n" );
document.write( "Let x represent the time in minutes it takes all three to fill the pool
\n" );
document.write( "Per minute is the Equalizer***
\n" );
document.write( "1/30 + 1/45 + 1/90 = 1/x  Multiplying all terms by 90x so as all denominators= 1
\n" );
document.write( "3x + 2x + x = 90
\n" );
document.write( "6x = 90
\n" );
document.write( "x = 15 minutes, the time it takes all three to fill the pool\r
\n" );
document.write( "\n" );
document.write( "chaecking our answer
\n" );
document.write( "3/90 + 2/90 + 1/90 = 6/90 = 1/15
\n" );
document.write( " \n" );
