Orly's age is 4 years more than thrice Perla's age. Four years ago, Orly was four times as old as Perla was then. How old is each now?

Perla --- x
Orly ---- 3x+4
four yrs ago
perla -- x-4
orly ---- 3x+4 - 4 or 3x
"Four years ago, Orly was four times as old as Perla was then"
---> 3x = 4(x-4)
3x = 4x - 16
x = 16
So Perla is 16 and Orla is 52
now: Perla = 16, Orla = 52
4 yrs ago : Perla = 12, Orla = 48
Is 48 four times 12 ? YEA

Reiny i have some question if Perla is x=16 how about the solution for Orly

As I stated above, Orla is 52
I had defined his age as 3x+4, and 2(16)+4 = 52
