Let x= number of Tom's columns
\n" ); document.write( "Let y= number of David's columns\r
\n" ); document.write( "\n" ); document.write( "Tom and David have 480 marbles between them
\n" ); document.write( "Tom arranges them in columns with 6 in each column, and David arranges them with 9 in each column.
\n" ); document.write( "then
\n" ); document.write( "\"6x%2B9y=480\"
\n" ); document.write( "The total number of columns is 72.
\n" ); document.write( "then
\n" ); document.write( "\"x%2By=72\"
\n" ); document.write( "
