Step-by-step explanation:
According to the question,
A+B=8 ------- Equation 1
B+C=12--------Equation 2
C+A=16--------Equation 3
Now, According to Equation 3 and Equation 1
A= 16 - C , and A= 8 - B Respectively
16 - C = 8 - B
C - B = 8 -------Equation 4
According to Equation 2, C + B =12
Add Equation 2 and Equation 4
C + B = 12
+ C - B = 8
