Answer 2

Answer:

18, 12

Explanation:

Let's have R be Rene's age.

R

And we have a younger sister who is 6 years younger than Rene:

R−6

In 10 years, the sum of their ages will be 50. So in 10 years Rene will be:

R+10

and her sister will be

R−6+10

and the two added together will be 50:

(R+10)+(R−6+10)=50

How old are they now?

(R+10)+(R−6+10)=50

2R+14=50

2R=36

R=18

and her sister is

R−6=18 −6=12
