jylarai one year ago The Formula F=1.8C+32 gives the temperature in degrees Celsius (C). There is one temperature for which number of degrees Fahrenheit is equal to the number of degrees Celsius. Complete the equation you can solve to find that temperature and then use it to find the temperature

let x be equal reading for C and F. x=1.8x+32 1.8x-x=-32 .8x=32 $x=\frac{- 32 }{ .8 }=\frac{ -320 }{ 8 }=-40$ at -40 degree both Fahrenheit and Celsius show the same reading.
