Answer 2

Step-by-step explanation:

ANSWER

Let the age of Kareem and his son be x and y respectively

According to question ,  

x=3y⟶(i)

After 10 years,  

Age of Kareem =x+10

Age of his son =y+10

∴(x+10)+(y+10)=76

x+y=56⟶(ii)

x−3y=0

On subtracting , 4y=56

y=14 years old

putting value of y in ⟶(i)

x=3×14=42 years.

Hence the age of Kareem = 42 years

And his son's age will be = 14 years
