Answer 2

Answer:

Step-by-step explanation

Let the present age be x years

6 years ago the age was x-6 years

Thrice the age 6 years ago = 3(x-6)

Twice the present age = 2x

As per question if thrice the age 6 years ago us subtracted from twice the present age, the result us present age. So the equation becomes

2x - 3(x-6) = x

2x -3x +18 = x

2x -3x -x = -18

-2x = -18

x = -18/-2 = 9 years.
