Question

At what temperature the c and F scales are equal

Answer 1

°C = (°C * 9/5) + 32°C - (°C * 9/5) = 32-4/5 * °C = 32°C = -32 * 5/4°C = -40°F = (°F * 9/5) + 32°F - (°F * 9/5) = 32-4/5 * °F = 32°F = -32 * 5/4°F = -40.So -40 degrees is answer

Answer 2

To find the temperature when both are equal, we use an old algebra trick and just set ºF = ºC and solve one of the equations. So the temperature when both the Celsius and Fahrenheit scales are the same is -40 degrees.
