Let \"L\" be the number of pages of \"large\" type and \"S\" the number of pages of \"small\" type.\r
\n" ); document.write( "\n" ); document.write( "The total number of pages is: \r
\n" ); document.write( "\n" ); document.write( "\"L+%2B+S+=+21\" .....eq.1 \r
\n" ); document.write( "\n" ); document.write( "Rewrite as: \"L+=+21+-+S\"\r
\n" ); document.write( "\n" ); document.write( "The total number of words is: \r
\n" ); document.write( "\n" ); document.write( "\"1800L+%2B+2400S+=+48000\"....eq.2\r
\n" ); document.write( "\n" ); document.write( "Substitute the \"L+=+21S\" into the second equation and solve for \"S\".\r
\n" ); document.write( "\n" ); document.write( "\"1800%2821+S%29+%2B+2400S+=+48000\"
\n" ); document.write( "\"37800+-+1800S+%2B+2400S+=+48000\"
\n" ); document.write( "\"+600S+=+48000-37800\"
\n" ); document.write( "\"+600S+=+10200\"
\n" ); document.write( "\"+S+=+10200%2F600\"
\n" ); document.write( "\"+S+=+17\"...... The number of pages of small type.\r
\n" ); document.write( "\n" ); document.write( "\"L+=+21-S\"
\n" ); document.write( "\"L+=+21-17\"
\n" ); document.write( "\"L+=+4\"....... The number of pages of large type.\r
\n" ); document.write( "\n" ); document.write( "
