C = 5 (F - 32)/9
5 (F - 32) = 9C
5F - 160 = 9C
5F = 9C + 160
F = (9C + 160)/5
5 (F - 32) = 9C
5F - 160 = 9C
5F = 9C + 160
F = (9C + 160)/5

C = (5/9)(F-32)
F-32 = (9/5)C
F = (9/5)C + 32
F-32 = (9/5)C
F = (9/5)C + 32

9 C = 5 F - 160
5 F = 9 C + 160
F = (9/5) C + 32
5 F = 9 C + 160
F = (9/5) C + 32

C = 5 * (F - 32) / 9
9 * C = 9 * 5 * (F - 32) / 9
9C = 5 * (F - 32)
9C/5 = 5 * (F - 32) / 5
(9/5) * C = F - 32
32 + (9/5) * C = 32 + F - 32
32 + (9/5) * C = F
9 * C = 9 * 5 * (F - 32) / 9
9C = 5 * (F - 32)
9C/5 = 5 * (F - 32) / 5
(9/5) * C = F - 32
32 + (9/5) * C = 32 + F - 32
32 + (9/5) * C = F
