document.write( "So I will follow those instructions with x, 5x, and 6x\r\n" );
document.write( "\r\n" );
document.write( "1.  add them:   x + 5x + 6x = 12x\r\n" );
document.write( "2.  count the numbers:  x is one, 5x is two, and 6x is three. So there are 3 numbers.\r\n" );
document.write( "3.  divide by the number of numbers:   = 4x\r\n" );
document.write( "\r\n" );
document.write( "Now we are told that must equal to 8, so we write that 4x and then put = 8\r\n" );
document.write( "after it, like this\r\n" );
document.write( "\r\n" );
document.write( "     4x = 8\r\n" );
document.write( "\r\n" );
document.write( "Then we divide both sides by 4\r\n" );
