$\"+x%2F21+=+%28-15%29+%2F+%28-35%29+\"$
\n" ); document.write( "It would help to simplify the right side
\n" ); document.write( "(-) / (-) = (+)
\n" ); document.write( " $\"+x%2F21+=+15%2F35+\"$
\n" ); document.write( "Divide top and bottom of right side by $\"+5+\"$
\n" ); document.write( " $\"+x%2F21+=+3+%2F+7+\"$
\n" ); document.write( "Multiply both sides by $\"+7+\"$
\n" ); document.write( " $\"+x%2F3+=+3%2F1+\"$
\n" ); document.write( "Multiply both sides by $\"+3+\"$
\n" ); document.write( " $\"+x+=+9+\"$
