Answer:

David's age 14

Carmen's age 21

Step-by-step explanation:

let David's present age = x

Carmen's present age = x+12

five years ago

David's age = x-5

Carmen's age = x+12-5

= x+7

sum their age was 28

x-5+x+7=28

2x+2=28

x= 28/2

x=14

therefore David's present age = 14

Carmen's present age =24+7=21

To Find :-What are the present ages.Solution :-Let, the present age of Lani be xAnd, the present age of Reggie will be (x + 5)5 years ago,The age of Lani be x + 5And, the age of Reggie = x + 5 - 5 = xAccording to the question,⇒ \sf x - 5 + x =\: 28x−5+x=28

⇒ \sf x + x - 5 =\: 28x+x−5=28

⇒ \sf 2x =\: 28 + 52x=28+5

+5⇒ \sf 2x =\: 300x=30

30

30Hence, their present ages are,

30Hence, their present ages are,✧ Present age of Lani = x = 12 years
