\n" ); document.write( "2.\"20T%2B5F=775\"
\n" ); document.write( " Substitute eq. 1 into eq. 2,
\n" ); document.write( "\"20%28F%2B10%29%2B5F=775\"
\n" ); document.write( "\"20F%2B200%2B5F=775\"
\n" ); document.write( "\"25F=575\"
\n" ); document.write( "\"highlight%28F=23%29\"
\n" ); document.write( "Then from eq. 1,
\n" ); document.write( "\"T=23%2B10\"
\n" ); document.write( "\"highlight%28T=33%29\"
