​

Answer 1

Answer:

After 16 years, Fatima will be thrice as old as she is at present. Since we take that variable x as Fathima present age, Hence the value of the variable x is equal to Fathima age at present. ∴The present age of Fathima is 8.

Answer 2

$\huge\boxed{\underline{\bf\green{A} \: \red{N} \: \orange{S} \: \purple{W} \: \blue{E} \: \pink{R}}}$

Let x be the present age of Fatima

According to Question :-

After 16 years , Fatima will be three times as old she is now

→ x + 16 = 3x

→ 3x - x = 16

→ 2x = 16

→ x = 16/2

→ x = 8

∴ Present age of Fatima is 8 years
