Question

Layla is 31 years older than Julia. The sum of their ages is 77. How old is Layla?

Answer 1

Explanation:

77-31=46

46/2=23

since layla is 31 years older add the 31 to 23 to get her age which is 54.

julia =23

layla=54

to check add their ages: 23+54=77

yes thats right since they have a difference of 31 (54-23=31)
