Let the number be $\"+n+\"$
\n" ); document.write( " $\"+7n+=+-20n+-+9+\"$
\n" ); document.write( "Add $\"+20n+\"$ to both sides
\n" ); document.write( " $\"+27n+=+-9+\"$
\n" ); document.write( " $\"+n+=+-+1%2F3+\"$
\n" ); document.write( "--------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+7n+=+-20n+-+9+\"$
\n" ); document.write( " $\"+7%2A%28-1%2F3%29+=+-20%2A%28-1%2F3%29+-+9+\"$
\n" ); document.write( "Multiply both sides by $\"+3+\"$
\n" ); document.write( " $\"+7%2A%28-1%29+=+%28-20%29%2A%28-1%29+-+9%2A3+\"$
\n" ); document.write( " $\"+-7+=+20+-+27+\"$
\n" ); document.write( " $\"+-7+=+-7+\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
