If you live in northern Canada, you are well aware of this oddity. It is quite often experienced in the north.
Solve
The trick is to make one of the letters the same as the other. That is
F = C

C = 1.8C + 32 Subtract 32 from both sides.
C - 32 = 1.8C Subtract C from both sides.
-32 = 1.8C - C
-32 = 0.8C Divide by 0.8 on both sides.
-32/0.8 = 0.8 C / 0.8
- 40 = C

So that means - 40C = - 40 F
