debbie is two years younger than john roxy is ten years older than john the sum of their ages is 53 how old is debbie

Answer 1

d = j-2

r = j+10

d+j+r = 53

j-2 +j + j+10 = 53

3j = 53-10+2 = 45

j = 45/3 = 15 years old = John's age

d =j-2 = 15-2 = 13 years old for Debbie's age

r=j+10 = 15+10 = 25 years old for Roxy's age

15+13+25 = 53
