Answer 2

Answer:

The required answer is 26.

Step-by-step explanation:

Given:-

A + A + A = 24 ____ (1)

A + B = 20 ____ (2)

2B + C = 30 ____ (3)

To find:-

The value of $A +B +C$.

From equation (1), we have

A + A + A = 24

3A = 24

A = 24/2

A = 8

Substitute the value of A in the equation (2) as follows:

⇒ 8 + B = 20

⇒ B = 20 - 8

⇒ B = 12

Now,

Substitute the value of B in the equation (3) as follows:

⇒ 2(12) + C = 30

⇒ 24 + C = 30

⇒ C = 30 - 24

⇒ C = 6

Then,

The value of $A+B+C$ is,

= 8 + 12 + 6

= 26

Therefore, the required answer is 26.
