-> Eng    A dealer sells 2/4 of a basket of eggs, less 5 eggs; If you add 37 eggs to those who remain will have 1/6 more than it had at the beginning. How many eggs did at the beginning? Regards

-> Esp   Un comerciante vende los 2/4 de un cesto de huevos, menos 5 huevos; si añade 37 huevos a los que le quedan tendrá 1/6 más de los que tenía al principio. ¿Cuántos huevos tenía al principio? Saludos cordiales.

X = Total eggs


37 + (1/2 X + 5) = 7/6 X
42 = (7/6 - 1/2) X
42 = 2/3 X
42*3/2 = X
63 = X

Muchas gracias Agus.

(2/4X+5)+37=1/6X+X
