Let $\"x\"$ = number of pages in 1st book
\n" ); document.write( " $\"2400\"$ = total pages in both books
\n" ); document.write( " $\"2400+-+x\"$ = number of pages in 2nd book
\n" ); document.write( "given:
\n" ); document.write( " $\"x%2F%282400+-+x%29+=+3%2F5\"$
\n" ); document.write( "Multiply both sides by $\"5%2A%282400+-+x%29%7D%7D%0D%0A%7B%7B%7B5x+=+3%2A%282400+-+x%29\"$
\n" ); document.write( " $\"5x+=+7200+-+3x\"$
\n" ); document.write( " $\"8x+=+7200\"$
\n" ); document.write( " $\"x+=+900\"$
\n" ); document.write( " $\"2400+-+x+=+2400+-+900\"$
\n" ); document.write( " $\"2400+-+900+=+1500\"$
\n" ); document.write( "The books have 900 pages and 1500 pages \n" ); document.write( "

\n" );
