$\"+a+-+3b+=+9b+-+7a+\"$
\n" ); document.write( "Add $\"+7a+\"$ to both sides
\n" ); document.write( " $\"+8a+-+3b+=+9b+\"$
\n" ); document.write( "Add $\"+3b+\"$ to both sides
\n" ); document.write( " $\"+8a+=+12b+\"$
\n" ); document.write( "Divide both sides by $\"+b+\"$
\n" ); document.write( " $\"+8%2A%28+a%2Fb+%29+=+12+\"$
\n" ); document.write( "Divide both sides by $\"+8+\"$
\n" ); document.write( " $\"+a%2Fb+=+12%2F8+\"$
\n" ); document.write( " $\"+a%2Fb+=+3%2F2+\"$
