Daniela is 23 years older than her daughter. in 5 years, their ages will total 63. how old are they now? i have an exam on this tomorrow ? !

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.
