let the present age of Sabrina be x
then the present age of Michal will be (x+6)
five years ago,
Michal's age was =(x+6)-5=x+1
and Sabrina's age was =x-5
therefore, according to the question,
x+1=3(x-5)
x+1=3x-15
16=2x
x=8
so Michal's present age =x+6=8+6=14 years
then the present age of Michal will be (x+6)
five years ago,
Michal's age was =(x+6)-5=x+1
and Sabrina's age was =x-5
therefore, according to the question,
x+1=3(x-5)
x+1=3x-15
16=2x
x=8
so Michal's present age =x+6=8+6=14 years
