Let daughter present age be x.
Daniela is 23 years older than her daughter.
Daniela present age = x+23
After 5 years daughter age will be x+5 and Daniela age will be x+23+5=28 years.
It is given sum of their ages after 5 years is 63.
Daughter age +Daniela age =63 (after 5 years)
x+5+x+28=63
Adding like terms :
2x+33=63
Subtracting 33 both sides
2x=63-33
2x=30
Dividing both sides by 2
x=15
Daughter present age x= 15
Daniela present age =x+23=15+23= 38 years.
