Do you mean adding the number straight or as a percentage? It's written as straight. In that case:
\n" ); document.write( "x - 0.3 + 0.4x +2.78 = 25
\n" ); document.write( "1.4x +2.48 = 25
\n" ); document.write( "1.4x = 22.52
\n" ); document.write( "x = 16.086
\n" ); document.write( ".
\n" ); document.write( "Can you please check to see that this is the correct wording of the problem? I'm suspecting that one or more of these should be percentages.
\n" ); document.write( "
\n" );
