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
