1) After 12 yrs i shall be 3times as
old as I was 4yrs ago.​

Answer 1

Answer:

12 years

Step-by-step explanation:

Let x = your current age

Translate:

"after 12 years i shall be 3 times as old i was 4 years ago"

(x+12) = 3 * (x-4)

Solution :

x+12 = 3(x-4)

x + 12 = 3x - 12 [distribute]

12 = 2x - 12 [subtract x from both sides]

24 = 2x [add 12 to both sides]

12 = x [divide both sides by 2]

Your current age is 12.

Check:

Is (12+12) = 3(12-4)

24 = 3(8)

24 = 24
