Answer:
Let the age of the woman be 'x' years
and the age of her son be 'y' years.
From 1 st condition,
x - y = 19........(i).
From 2 nd condition,
x + y = 37.........(ii).
Adding equation (i) and equation (ii)
x - y = 19
x + y = 37
2x = 56
x = 56/2
x = 28
Place x = 28 in equation (ii),
28 + y = 37
y = 37 - 28
y = 9
Therefore the age of the son is 9 years.
