Answer:
Hope it helps!! Mark this answer as brainliest if u found it useful..
Step-by-step explanation:
If a+b=5 and b+c = 6, then we know that the value of c must be one more than a, as b stays the same, but the value is higher..
(b = 5-a, b = 6-c, so 5-a = 6-c, 5-a+c = 6, 5+c = 6+a, c = a+1).
So, we know that a + c is 7, and c is one more than a, so a+a+1 = 7. 2a = 6, so a = 3.
(If we check, it all works out
3+b = 5, so b is 2.
2+c = 6, so c is 4.
3 plus 4 is 7.)

Answer:
a = 3
Step-by-step explanation:
a + b = 5
b + c = 6
c + a = 7
if a + b =3 + 2 = 5
b + c = 2 + 4 = 6
c + a = 4 + 3 = 7
a = 3
