Flowers

The flower has six flowers and each flower has a number. These are the numbers: 20,40,39,28,8,9. What number will be in the middle of the flower so that the numbers come from the flowers when we subtract and add?

Correct result:

x =  48

Solution:

x=39+9=48 a1=x20=4820=28 a2=x40=4840=8 a3=x39=4839=9 a4=x28=4828=20 a5=x8=488=40 a6=x9=489=39
