Answer:
Step-by-step explanation:
a+b+b+c+c+a= 7+8+9
therefore 2[ a+b+c ] = 24
hence a+b+c is 12
mean = a+b+c/3 = 12/3 = 4.

Take a as 4
So 4+3=7
So a=4
b+c=8
We can also take 4+4 but further it will have difficulties
So we will take 5+3=8
b=3
c=5
c+a
5+4
This is the answer
So 4+3=7
So a=4
b+c=8
We can also take 4+4 but further it will have difficulties
So we will take 5+3=8
b=3
c=5
c+a
5+4
This is the answer
