$\"x\"$ = number of girls in the class
\n" ); document.write( " $\"18\"$ = number of boys in the class
\n" ); document.write( "We are told that
\n" ); document.write( " $\"18=x-w\"$ <---> $\"18%2Bw=x\"$
\n" ); document.write( "We need to find out the number of students in the class.
\n" ); document.write( "We expect that all the boys and girls in the class are students,
\n" ); document.write( "and that every students in the class is either a boy or a girl,
\n" ); document.write( "so
\n" ); document.write( " $\"s=18%2Bx\"$ = number of students in the class
\n" ); document.write( "substituting $\"18%2Bw\"$ for $\"x\"$ ,
\n" ); document.write( " $\"s=18%2B%2818%2Bw%29\"$
\n" ); document.write( " $\"s=%2818%2B18%29%2Bw\"$
\n" ); document.write( " $\"s=highlight%2836%2Bw%29\"$ \n" ); document.write( "

\n" );
