In 5 years, dad will be three times as old as his daughter jill will be then. if the sum of their present ages is 50, how old are they now? if y + 5 is jill's age five years from now, which of the following equations could be used to solve the problem?

Dad's current age is 40 years and Jill's age is 10 years.

Step-by-step explanation:

Let Dad's current age be = x

Let Jill's current age be = y

The sum of their present ages = 50

We get :  or  

In 5 years, Dad will be three times as old as his daughter Jill will be then.

Putting the value of x here;

=>

=>

=>

y = 10

And  

x = 40

Hence, dad's current age is 40 years and Jill's age is 10 years.
