Step-by-step explanation:
Both children age campare with Fatima age so
Fatima age = x
Nazir age. = x + 2
Mustafa age = x + 5
So the equation is
Fatima age + nazir age+ Mustafa age = father age
(x) + (x + 2) + ( x + 5) = 43
x + x + x + 2 + 5 = 43
3x + 7 = 43
3x = 43 - 7
3x = 36
x = 36/3
x = 12
So
Fatima age = 12
Nazir age = x +2
= 12 + 2
= 14
Mustafa age = x + 5
= 12 + 5
= 17
