You can put this solution on YOUR website! Reggie's age = "x+5"
why? because laarni's age = "x"
Five years ago: ----------------> working eqn
substract 5 yrs from their ages and sum up to 25.
Continuing: -------------------------> Laarnis' age ------------------> reggie's age
To check, 5 years ago: Go back working eqn
Thank you,
