Answer 2

Given:

A+A+A=3

B+B+A=5

C+C+B=8

To find:

A+B*C=?

Solution:

Finding the value of A:

A+A+A=3

3A = 3

A = 3/3

A = 1.

Finding the value of B:

B+B+A=5

2B + 1 = 5

2B = 4

B = 4/2

B = 2

Finding the value of C:

C+C+B=8

2C + 2 = 8

2C = 6

C = 6/2

C = 3

Finding A+B*C=?

A+B*C = 1 + (2 x 3)

A+B*C = 1 + 6

A+B*C = 7

Hence, the required answer is 7.
