Let day 1 = d, day 2 = 2d,and day 3 = 4d
\n" ); document.write( "So, we get
\n" ); document.write( " $\"d+%2B+2d+%2B+4d+=+210\"$
\n" ); document.write( "step 1 - combine like terms to get
\n" ); document.write( " $\"7d+=+210\"$
\n" ); document.write( "step 2 - divide to get
\n" ); document.write( " $\"d+=+30\"$
\n" ); document.write( "day 1 = 30
\n" ); document.write( "day 2 = 60
\n" ); document.write( "day 3 = 120 \n" ); document.write( "
