Let \"+x+\" = the number of pages in the book
\n" ); document.write( "\"I read 2/3 of a book on first day\"
\n" ); document.write( "That is \"+%282%2F3%29%2Ax+\"
\n" ); document.write( "That leaves 1/3 of the pages left
\n" ); document.write( "That is \"+%281%2F3%29%2Ax+\"
\n" ); document.write( "3/5 of the remaining pages is:
\n" ); document.write( "\"+%283%2F5%29%2A%281%2F3%29%2Ax+=+%281%2F5%29%2Ax+\"
\n" ); document.write( "------------------------------
\n" ); document.write( "Now I can say:
\n" ); document.write( "\"+%282%2F3%29%2Ax+%2B+%281%2F5%29%2Ax+%2B+40+=+x+\"
\n" ); document.write( "Multiply both sides by \"+15+\"
\n" ); document.write( "\"+10x+%2B+3x+%2B+600+=+15x+\"
\n" ); document.write( "\"+2x+=+600+\"
\n" ); document.write( "\"+x+=+300+\"
\n" ); document.write( "The book has 300 pages
\n" ); document.write( "---------------------------
\n" ); document.write( "check:
\n" ); document.write( "\"+%282%2F3%29%2A300+=+200+\" pages on the 1st day
\n" ); document.write( "There are 100 pages left
\n" ); document.write( "\"+%283%2F5%29%2A100+=+60+\" pages on the 2nd day
\n" ); document.write( "There are \"+300+-+260+=+40+\" pages left
\n" ); document.write( "That is correct
\n" ); document.write( "
\n" ); document.write( "
\n" );
