Darisa is 10 years older than Adahun. 10 years from now, Darisa would be twice as old as Adahun was 10 years ago. How old would be after 12 years?

Answer 1

Now:
Adahun ----- x
Darissa ---- x+10

10 years from now:
Darissa ----- x+20

10 years ago:
Adahumn ---- x-10

"10 years from now, Darisa would be twice as old as Adahun was 10 years ago" ----> x+20 = 2(x-10)
