Let's make the number of girls g and the number of boys b.\r
\n" ); document.write( "\n" ); document.write( "\"g%2Bb=466\"\r
\n" ); document.write( "\n" ); document.write( "There are 212 more girls than boys so:\r
\n" ); document.write( "\n" ); document.write( "\"g=b%2B212\"\r
\n" ); document.write( "\n" ); document.write( "If we substitute this value for g into the first equation we get:\r
\n" ); document.write( "\n" ); document.write( "\"%28b%2B212%29%2Bb=466\"\r
\n" ); document.write( "\n" ); document.write( "Get rid of the brackets:\r
\n" ); document.write( "\n" ); document.write( "\"b%2B212%2Bb=466\"\r
\n" ); document.write( "\n" ); document.write( "Add like terms:\r
\n" ); document.write( "\n" ); document.write( "\"2b%2B212=466\"\r
\n" ); document.write( "\n" ); document.write( "Subtract 212 from each side:\r
\n" ); document.write( "\n" ); document.write( "\"2b=254\"\r
\n" ); document.write( "\n" ); document.write( "Divide by 2:\r
\n" ); document.write( "\n" ); document.write( "\"b=127\"\r
\n" ); document.write( "\n" ); document.write( "So the number of boys in the class is 127.
\n" ); document.write( "
