their present ages.

please write and give​

Answer 1

Step-by-step explanation:

Let the present age of Amina be x

Therefore,2x-6=4(x-6)

2x-6=4x-24

2x-4x=-24+6

-2x=-18

x=9

so,present age of amina is 9 and that of arun is 2×9=18

Answer 2

Answer:

Let Shriya's present age is x years. Then, Arjun's present age will be 2x years.

Five years ago,

3(x−5)=(2x−5)

3x−15=2x−5⇒x=10

Shriya's present age is 10 years.

Arjun's present age is 20 years.
