Question

after 24 years i shall be 3 times as old as i was 4 years ago find my present age

Answer 1

x + 24 = 3 (x-4)
x + 24 = 3x - 12
x - 3x = -12 - 24
-2x = -36
x = -36/-2
= 18.

Answer 2

$\textbf{Solution :}$
__________

Let my present age be $\textbf{x years}$

According To Question [A.T.Q]

“[Me (x)] [After (+)] 24 years [shall (=)] be [3 times (×)] as [I (x)] [was (-)] 4 years ago”

x + 24 = 3(x - 4)

=> x + 24 = 3x - 12

=> x - 3x = - 12 - 24

=> - 2x = - 36

=> 2x = 36

$= > x = \frac{36}{2}$

=> x = 18

•°• My present age = x years
= $\textbf{18 years}$
