When 1/5 of the boys left, there were still b boys and g girls who stayed to see
\n" ); document.write( "the end of the program. What was the total number of boys and girls at the beginning of the program?
\n" ); document.write( "

\r\n" );
document.write( "The problem doesn't say that any girls left, so we'll assume that no girls\r\n" );
document.write( "left, and so there were also g girls at the beginning of the program.\r\n" );
document.write( "\r\n" );
document.write( "Let x = the number of boys at the beginning of the program.\r\n" );
document.write( "\r\n" );
document.write( "Then we subtract one-fifth of x from x to get b boys: \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Multiply through by 5:\r\n" );
document.write( "\r\n" );

document.write( "Checking:\r\n" );
document.write( "There were  boys at the beginning, then  left,\r\n" );
document.write( "and so there were  boys at the end.\r\n" );
document.write( "\r\n" );
document.write( "Answer:  boys and g girls at the beginning.\r\n" );
