Karen is 6 yrs older than her sister Michelle and Michelle is two years younger than their brother David If the sum of their age
frosja888 [35]
You are told the ages of Karen and David in terms of Michelle's age.
Let m = Michelle's age.

Michelle's age = m
Karen's age = m + 6

Michelle is two years younger than David, so David is two years older than Michelle.

David's age = m + 2

Add the ages and get 62.

m + m + 6 + m + 2 = 62

3m + 8 = 62

3m = 54

m = 18

Michelle is 18 years old

Karen is 6 years older, so she is 24 years old.

David is 2 years older than Michelle, so he is 20 years old.

lets multiply b+c=30 by -20

-20b-20c=-600

if we substract that from
