Solution, to the formula 14-6=8 (a)

0+8=8 1+7=8 2+6=8 3+5=8 4+4=8 5+3=8 6+2=8 7+ 1=8 8+0=8

According to the formula, 4+4=8.

So 6+4= 10 (piece)

14-4= 10 (piece)

10= 10

Xiao Jia wants to give Lily four balloons. They have as many balloons.

If the last two people are required to have the same number of balloons, then calculate the number of balloons combined by two people, and the last person gets half of the total, and then the person with more balloons subtracts half of the total, which is the number of balloons Michelle wants to give to Lili.

Total number of balloons = number of balloons in Jony J+number of balloons in Lili =14+6 = 20;

Half of the total number of balloons =20 = 10 balloons;

The number of balloons Xiao Jia wants to give Lily = the number of balloons Xiao Jia-half of the total number of balloons = 14- 10 = 4.

Checking calculation: Xiao Jia's current balloon number =14-4 =10.

Lily's current balloon number =6+4= 10.

The number of balloons is equal, so the result is correct.
