  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 - ,
  
  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 = 10-3 = 7 years
  
  So if John is 7 years as of now, he will be 8 years olf on his next birthday.
