w = 3(2a + b) - 4
First, add 4 to both sides:
w (+4) = 3(2a + b) - 4 (+4)
w + 4 = 3(2a + b)
Next, divide 3 from both sides:
(w + 4)/3 = (3(2a + b))/3
(w + 4)/3 = 2a + b
Next, subtract b from both sides:
((w + 4)/3) - b = 2a + b (-b)
(w + 4)/3 - b = 2a
Finally, divide 2 from both sides:
((w + 4)/3 - b)/2 = (2a)/2
a = (((w + 4)/3) - b)/2
a = (((w + 4)/3) - b)/2 is your answer.

The formula for circular permutation is given by (n-1)!
This is because of the fact that in a circular setting if you move each of the person one way right or left, you still get the same arrangement, and we can do so n times until we get back to the first arrangement.
S1 = x
s2 = 2x
s3 = 3x - 3
51 = s1 + s2 + s3
51 = x + 2x + 3x - 3
54 = 6x
9 = x
