Present age - y
After 3 years his age be y + 3.
Before 2 years his age was y - 2.
Now ,A/Q,
y + 3 = 2(y - 2)
y + 3 = 2y - 4
y = 7
so his present age is 7 years.

From question,
In 3 years time, Danny's year also increases by 3
i.e., y+3
now,at this age(y+3),
he would be twice as old as he was 2yrs ago,
i.e.,
(y+3)=2×(present age - 2)
OR
(y+3)= 2×(y-2)......THIS IS THE EQUATION..☺️
Now on solving.....
y+3 = 2y-4
2y-y = 4+3
i.e.,
☺️y = 7 ☺️
