The sum of the page numbers on facing pages of a book is 157: what are the page numbers.\r
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "Let the left page be page number N\r\n" );
document.write( "\r\n" );
document.write( "Then the right page is page number N+1\r\n" );
document.write( "\r\n" );
document.write( "The sum of the pages is N + (N+1)\r\n" );
document.write( "\r\n" );
document.write( "So the equation is\r\n" );
document.write( "\r\n" );
document.write( "N + (N+1) = 157\r\n" );
document.write( "\r\n" );
document.write( "N + N + 1 = 157\r\n" );
document.write( "\r\n" );
document.write( "2N + 1 = 157\r\n" );
document.write( "\r\n" );
document.write( "    2N = 156\r\n" );
document.write( "\r\n" );
document.write( "     N = 78\r\n" );
document.write( "\r\n" );
document.write( "So the page on the left is page 78 and\r\n" );
document.write( "the page on the right is 79.\r\n" );
