Steve, who lives in England, is reading a letter from his pen pal in the United States. His pen pal says that the temperature in his city was 37.4° Fahrenheit one day, so it was too cold to play rugby outside. Steve doesn't know how cold this is, because he is used to temperatures in Celsius. Help Steve solve the following equation to determine the temperature in degrees Celsius: 1.8C+32=37.4. Round your answer to the nearest tenth of a degree.
