Answer:

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.
