document.write( "Let     W       is the width.\r\n" );
document.write( "\r\n" );
document.write( "Then    3W - 2  is the length.\r\n" );

document.write( "\r\n" );
document.write( "Multiply both sides by 3\r\n" );
document.write( "\r\n" );
document.write( "   3W*(3W-2) = 48.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the number 48 is presented as the product of two factors what differ by 2.\r\n" );

document.write( "If you think 5 seconds, you guess these numbers: 6 and 8.\r\n" );

document.write( "\r\n" );
document.write( "Hence,  3W = 8  and then  W =  = 2 .\r\n" );
