Hi there, in order to figure this out look at the sum 70. If you want to find the age your going to have to break it down. So, to figure this out I found that Sharon is 14. It took me a while, using different numbers but I worked with 14 and multiplied it by four and found that John is 56, making that x4 older than Sharon. If you divide 56 by 4, you'll get 14, just to check your answer. And to make sure this is correct I added 56 and 14 together to get 70.
