Y = Numero original de mujeres
Pero Y = 3X (Ecuacion 1)
Se retiran 8 parejas
X - 8
Y - 8
5(X - 8) = (Y - 8)
5X - 40 = Y - 8 (Ecuacion 2)
Reemplazo Y = 3X
5X - 40 = 3X - 8
5X - 3X = 40 - 8
2X = 32
X = 16
Y = 3(16)
Y = 48
Probemos
16 - 8 = 8
48 - 8 = 40
5(8) = 40
40 = 40
Rta: Incialmente habia 16 Hombres y 48 Mujeres
