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