Helen is 8 years older than jane. twenty years ago helen was three times as old as jane. how old is each now?

Let the age of the Jane be

So age of Helen =   + 8

Twenty years ago,

Age of Jane = - 20

And age of Helen = + 8 - 20 = - 12

Helen was three times as old as Jane

- 12 = 3 ( - 20)

- 12 = 3 - 60

Add - 3 on both sides,

- 3 - 12 = 3 - 3 - 60

-2 - 12 = - 60

Add  12 on both sides

-2 - 12  + 12 = - 60 + 12

-2 = - 48

Divide both side by -2

= 24

Age of Jane = 24 yrs

Age of Helen = 32 yrs

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
