john is the age that sally was 3 years ago,13 year old elissa is 3 years older than sally,how old will john be on his next birthday?

math 
Lena,
John's age = Sally's age  3 years
Elissa's age = 13 years
Sally's age = Elissa's age  3 years = 13 3 = 10 years
Now that we know Sally's current age, we can figure out John's age.
John's age = 103 = 7 years
So if John is 7 years as of now, he will be 8 years olf on his next birthday.
