Fahrenheit increases at approximately twice the rate of Celsius. (ΔF=1.8ΔC), And freezing for Fahrenheit is 32° (32°F=0°C). Using these facts, we can find the conversion equation F=1.8C+32. Since this is a linear polynomial, there is exactly 1 intersection with the function F=C, which we can find by solving it as a system of equations:

IF C=F AND F=1.8C+32 THEN C=1.8C+32.

C=1.8C+32

C-1.8C=32

-.8C=32

(-8/10)C=32

C=32*(-10/8)

=-32*10/8 [If you're using a calculator, this is probably your input.]

=-10*32/8

=-10* (32/8)

=-10* (2^(5)/2^(3))

=-10* (2^(5-3))

=-10* 2^2

=-10* 2*2

=-10* 4

=-40

∴ -40°C = -40°F.
