A = B + 5/12 ....... EQ (1)
C = B - 9/24 ...... EQ (2)
EQ(1) - EQ(2) BECOME
A - C = (B + 5/12) - (B - 9/24)
=> A - C = 5/12 + 9/24
C = B - 9/24 ...... EQ (2)
EQ(1) - EQ(2) BECOME
A - C = (B + 5/12) - (B - 9/24)
=> A - C = 5/12 + 9/24

A = B + 5/12
C = B - 9/24
A - C = 5/12 + 9/24 = 19/24
C = B - 9/24
A - C = 5/12 + 9/24 = 19/24
