La suma de las edades de una madre y de su hijo son 56 años. Hace 10 años, la edad de la madre era el quíntuple de la edad que tenía el hijo. ¿Cuál es la edad actual de cada uno?

The mother is 40 years old and the son is 16 years old.

Step-by-step explanation:

With a system of equations mentioned in the statement the answer can be reached, we have to:

Let X be the age of the mother, Y the age of the son.

X + Y = 56 (1)

X-10 = 5 * (Y-10) (2)

Solving

 X -10 = 5 * Y - 50

From where:

X = 5 * Y - 40

Substituting in the first equation:

5 * Y - 40 + Y = 56

6 * Y = 56 + 40

Y = 96/6 = 16

Now, replacing the value of Y:

X = 5 * 16 - 40

X = 80 -40

X = 40

Therefore the mother is 40 years old and the son is 16 years old.
