There are an equal number of boys and girls in a class. If there were 6 fewer boys and 6 more girls, there would be twice as many girls as boys. How many students are in the class?
\n" ); document.write( ":
\n" ); document.write( "Let b = no. of boys
\n" ); document.write( " &
\n" ); document.write( "g = no. of girls
\n" ); document.write( ":
\n" ); document.write( "(g + 6) = 2(b - 6)
\n" ); document.write( "g + 6 = 2b - 12
\n" ); document.write( "g = 2b - 12 - 6
\n" ); document.write( "g = 2b - 18
\n" ); document.write( "we know b = g, therefore:
\n" ); document.write( "b = 2b - 18
\n" ); document.write( "b - 2b = -18
\n" ); document.write( "-b = -18
\n" ); document.write( "b = 18 boys and 18 girls, a total of 36 in the class
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "check: (18+6) = 2(18-6) \n" ); document.write( "
\n" );
