Let $\"+x+\"$ = the unknown number
\n" ); document.write( "Add $\"+7+\"$
\n" ); document.write( " $\"+x+%2B+7+\"$
\n" ); document.write( "Double the result
\n" ); document.write( " $\"+2%2A%28+x+%2B+7+%29+\"$
\n" ); document.write( "This equals $\"+34+\"$
\n" ); document.write( " $\"+2%2A%28+x+%2B+7+%29+=+34+\"$
\n" ); document.write( "---------------------------
\n" ); document.write( "Divide both sides by $\"+2+\"$
\n" ); document.write( " $\"+x+%2B+7+=+17+\"$
\n" ); document.write( "Subtract $\"+7+\"$ from both sides
\n" ); document.write( " $\"+x+=+10+\"$
\n" ); document.write( "The number is 10
\n" ); document.write( " \n" ); document.write( "

\n" );
