Let $\"+x+\"$ = the unknown number
\n" ); document.write( " $\"+%28%28+63+-+x+%29%29+%2F4+=+2x+\"$
\n" ); document.write( "Multiply both sides by $\"+4+\"$
\n" ); document.write( " $\"+63+-+x+=+8x+\"$
\n" ); document.write( "Add $\"+x+\"$ to both sides
\n" ); document.write( " $\"+63+=+9x+\"$
\n" ); document.write( "Divide both sides by $\"+9+\"$
\n" ); document.write( " $\"+7+=+x+\"$
\n" ); document.write( "----------
\n" ); document.write( "The unknown number is 7
\n" ); document.write( "----------

\n" ); document.write( "When a number is subtracted from 63
\n" ); document.write( " $\"+63+-+7+=+56+\"$
\n" ); document.write( "and the result is divided by 4
\n" ); document.write( " $\"+56%2F4+=+14+\"$
\n" ); document.write( "The answer obtained is twice the original number
\n" ); document.write( " $\"+14+=+2%2A7+\"$
\n" ); document.write( "OK \n" ); document.write( "
