$\huge\green{Answer}$

Let the present age of Trisha be x

Trisha's age 9 years ago=x-9

Trisha's age after three years =x+3

It is given that Trisha's age after 3 years =3(x-9)

x+3=3(x-9)

x+3=3x-27

27+3=3x-x

30=2x

30/2=x

15=x

x=15

Present age of Trisha =x=15years

Answer 2

Answer:

HERE IS THE ANSWER TO THE ABOVE QUESTION....

Step-by-step explanation:

Let the present age of Trisha be x.

So, after three years, her age will be (x+3) years.

Nine years ago, her age was (x-9) years.

Therefore, after three years, her age will be 3(x-9) years.

According to problem,

(x+3) = 3(x-9)

=> x+3 = 3x-27

=> 3x-x = 27+3

=> 2x = 30

Therefore, x = 30/2

= 15

So, Trisha's present age is 15 years.
