Answer:
a + b = 29 ----(1)
b + c = 45 ---(2)
a + c = 44 -----(3)
adding eq (1) , (2) and (3)
a + b + b + c + a + c = 29 + 45 + 44
2a + 2b + 2c = 118
2 ( a + b + c ) = 118
a + b + c = 118 / 2
a + b + c = 59
a + b + c = 59
hope it helps

Given,
- a + b = 29
- b + c = 45
- a + c = 44
To Find,
- Value of a + b + c
Solution :
Give three Equation in this Question :-
- a + b = 29 1) Equation
- b + c = 45 2) Equation
- a + c = 44 3) Equation
║Now Add All this three Equation║
Firstly we Add the Equation First and Third :-
∴a + b = 29
(-)a +(-)c = (-)44
b - c = -15
∴b = 15 + c
Now Put the Value of b in Second Equation :-
∴ b + c = 45
⇒-15 + c + c = 45
⇒2c = 45 + 15
⇒2c = 60
⇒c = 30
Therefore,
⇒ b = 15 + c
⇒b = 15 + 30
⇒b = 45
Now Put the value of b in First Equation :-
⇒a + b = 29
⇒a + 45 = 29
⇒a = 29 - 45
⇒a = -16
Therefore,
