Question

After 12 years, I shall be 3 times as old as I was 4 years ago. Find my present age​

Answer 1

Answer:

12

Step-by-step explanation:

let the present age be x

therefore,

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

x + 12 = 3x - 12

x-3x+12+12 = 0

-2x+24=0

-2x = -24

x = 24/2

x = 12

Answer 2

Step-by-step explanation:

x+12=3(x-4)

x+12=3x-12

12+12=3x-x

24=2x

x=12
