According to the question
hope it helps
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.
