A + 5 star = 6 stars
A + B = 3 stars
B + C = A + 2 stars
- A = _____ stars
- B = _____ stars
- C = _____ stars
A + 5 star = 6 stars --- (1)
A + B = 3 stars --- (2)
B + C = A + 2 stars --- (3)
(a)
From (1)
A + 5 star = 6 stars
A = 6 stars - 5 star
A = 1 stars
(b)
Substitute A = 1 stars into (2).
A + B = 3 stars
1 stars + B = 3 stars
B = 3 stars - 1 stars
B = 2 stars
(c)
Substitute A = 1 stars and B = 2 stars into (3).
B + C = A + 2 stars
2 stars + C = 1 stars + 2 stars
2 stars + C = 3 stars
C = 3 stars - 2 stars
C = 1 stars
Answer(s): (a) 1; (b) 2; (c) 1
