1/a + 2/b = 3/c\r
\n" ); document.write( "\n" ); document.write( "2/b = 3/c - 1/a\r
\n" ); document.write( "\n" ); document.write( "2/b = (3a - c)/ca\r
\n" ); document.write( "\n" ); document.write( "2ca = b(3a-c)\r
\n" ); document.write( "\n" ); document.write( "b = 2ca/(3a-c)
\n" ); document.write( "
\n" );
