solve for x:
\n" ); document.write( "ax+by=c\r
\n" ); document.write( "\n" ); document.write( "1. subtract by from both sides
\n" ); document.write( " ax = c - by
\n" ); document.write( "2. divide both sides by a
\n" ); document.write( " x = c - by / a\r
\n" ); document.write( "\n" ); document.write( "Teachers use this trick to see if students really know what they're doing
