➠ My present age.

★ SolutioN :

Let my present age be xx

★ Given ThaT :

∴ After 2424 years, my age will be ( x + 24 )(x+24) years. 44 ago, my age will be ( x - 4)(x−4)

(x + 24) = 3(x - 4)(x+24)=3(x−4)

x + 24 = 3x - 12x+24=3x−12

x - 3x = ( - 12 - 24)x−3x=(−12−24)

- 2x = - 36−2x=−36

x = \frac{ - 36}{ - 2}x=

−2
