Simply rearrange all the \"m\" terms together and all the \"n\" terms together:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "12m + 3n - 9m - 7n\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "= (12m - 9m) + (3n - 7n)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "= 3m - 4n
\n" ); document.write( "
\n" );
