A + 5 square = 9 squares
A + B = 8 squares
B + C = A + 5 squares
- A = _____ squares
- B = _____ squares
- C = _____ squares
A + 5 square = 9 squares --- (1)
A + B = 8 squares --- (2)
B + C = A + 5 squares --- (3)
(a)
From (1)
A + 5 square = 9 squares
A = 9 squares - 5 square
A = 4 squares
(b)
Substitute A = 4 squares into (2).
A + B = 8 squares
4 squares + B = 8 squares
B = 8 squares - 4 squares
B = 4 squares
(c)
Substitute A = 4 squares and B = 4 squares into (3).
B + C = A + 5 squares
4 squares + C = 4 squares + 5 squares
4 squares + C = 9 squares
C = 9 squares - 4 squares
C = 5 squares
Answer(s): (a) 4; (b) 4; (c) 5
