 <a class="tooltip c:2815439-2" href="https://www.meneame.net/m/Problemas/problema-40-papiro-rhind/c02#c-2" rel="nofollow">#2</a>  Por supuesto con matemáticas modernas, notación algebraica etc es un problema muy sencillo, pero en su época y con sus herramientas era bastante complejo. No lo pongo aquí por su dificultad sino por su valor histórico.</p><p>&#187;&nbsp;autor: <strong>fantomax</strong></p>]]></description>

<br />
Es un simple sistema de dos ecuaciones con dos incógnitas:<br />
x + (x+d) + (x+2d) + (x+3d) + (x+4d) = 100<br />
5x + 10d = 100 -&#62; x + 2d = 20<br />
<br />
((x+4d) + (x+3d) + (x+2d))/7 = x + x+d<br />
(3x+9d)/7 = 2x + d -&#62; (3x/7 - 2x) + (9d/7 - d) = 0 -&#62; -11x/7 + 2d/7 = 0<br />
<br />
x = 20 - 2d<br />
<br />
-11(20 - 2d)/7 + 2d/7 = 0 -&#62; (-220 + 24d)/7 = 0 -&#62; d = 220/24 = 55/6<br />
<br />
x = 20 - 110/6 = 10/6 = 5/3</p><p>&#187;&nbsp;autor: <strong>--99674--</strong></p>]]></description>
