\r\n" );
document.write( "Let x be her score on her 5the test.\r\n" );
document.write( "\r\n" );
document.write( "Then the score on her 6th test was (x-4), according to the condition.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Next, you write the equation for the average for six math tests\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "     = 87.\r\n" );
