\n" ); document.write( "You are in line at a ticket window.
\n" ); document.write( "Cool,then?
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "There are two more people ahead of you than there are behind you.
\n" ); document.write( "Let the people behind you be x number of people.
\n" ); document.write( "Then the number of people ahead of you are (x+2).
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "In the entire line, there are three times as many people as there are behind you.
\n" ); document.write( "so the number of people behind you is x
\n" ); document.write( "the entire line has three times x people = 3x
\n" ); document.write( "
\n" ); document.write( "How many people are ahead of you in line?
\n" ); document.write( "Look at it this way:
\n" ); document.write( "you have (x+2) people ahead of you
\n" ); document.write( "then you are standing there
\n" ); document.write( "then you have x number of people behind you
\n" ); document.write( "**so all these people put together make the total number of people in the line.
\n" ); document.write( "total number of people=(x+2)+1+x=(2x+3)
\n" ); document.write( "but the question tell us that total number of people in the line is 3x
\n" ); document.write( "**so we get,
\n" ); document.write( "3x=2x+3
\n" ); document.write( "3x-2x=3
\n" ); document.write( "x=3
\n" ); document.write( "
\n" );
document.write( "remember x stands for the people behind you in the line
\n" );
document.write( "so you have 3 people behind you in the line
\n" );
document.write( "the question says there are (x+2) people ahead of you
\n" );
document.write( "so there are (3+2)=5 people ahead of you in the line.
