Question

Nancy is 15 years older than Edward, but in 3 more years she will be 8 times as old as he was 3 years ago. how old are they now?​

Answer 1

Answer:

Edward is 6 years old and Nancy is 21 years old

Step-by-step explanation:

Let Nancy's age be 'N' and Edwards age be 'E'

N=E+15;

N+3=8(E-3);

By substituting the value of N into the second equation, we are able to determine both the ages

Answer 2

Answer:

Edward's age=6years

Nancy's age = 15+6=21 years

Step-by-step explanation:

Let age of Edward be = x

and age of Nancy be = x+15

Now,

Age of Nancy after 3 years = x+15+3years=x+18years

and

Age of Edward 3 years ago = x-3

years

Now According to the question,

8(x-3) =x+18

8x-24=x+18

8x-x=18+24

7x=42

x=42/7

x=6ans
