A + 4 square = 6 squares
A + B = 3 squares
B + C = A + 4 squares
- A = _____ squares
- B = _____ squares
- C = _____ squares
A + 4 square = 6 squares --- (1)
A + B = 3 squares --- (2)
B + C = A + 4 squares --- (3)
(a)
From (1)
A + 4 square = 6 squares
A = 6 squares - 4 square
A = 2 squares
(b)
Substitute A = 2 squares into (2).
A + B = 3 squares
2 squares + B = 3 squares
B = 3 squares - 2 squares
B = 1 squares
(c)
Substitute A = 2 squares and B = 1 squares into (3).
B + C = A + 4 squares
1 squares + C = 2 squares + 4 squares
1 squares + C = 6 squares
C = 6 squares - 1 squares
C = 5 squares
Answer(s): (a) 2; (b) 1; (c) 5
