System: $\"highlight%28x%2By=35%29\"$ and $\"highlight%28%2860x%2B90y%29%2F35=72%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Maybe continue like $\"60x%2B90y=35%2A72\"$ , $\"y=35-x\"$
\n" ); document.write( " $\"60x%2B90%2835-x%29=35%2A72\"$
\n" ); document.write( " $\"6x%2B90%2A35-90x=35%2A72\"$
\n" ); document.write( " $\"6x-90x=35%2A72-90%2A35\"$
\n" ); document.write( " $\"%2890-6%29x=%2890-72%2935\"$
\n" ); document.write( " $\"86x=18%2A35\"$
\n" ); document.write( " $\"highlight%28x=9%2A35%2F43%29\"$
\n" ); document.write( ".
