The equation to convert from degrees Celsius to degrees Fahrenheit is F=1.8C+32, whereas a simpler estimate for this conversion is F=2C+30. By solving each of these equations for C, we can convert from degrees Fahrenheit to degrees Celsius.

The answer to your question is  Equation 1  C = (F -32)/1.8

                                                      Equation 2   C = (F - 30)/2

Step-by-step explanation:

Data

Equation 1   F = 1.8C + 32

Equation 2  F = 2C + 30

Solve both equations for C

Equation 1

- Substract 32 in both sides

                  F - 32 = 1.8C + 32 - 32

- Simplify

                  F - 32 = 1.8C

- Divide both sides by 1.8

                  C = (F -32)/1.8

Equation 2

                   F = 2C + 30

- Substract 30 in both sides

                  F - 30 = 2C + 30 - 30

- Simplify

                  F - 30 = 2C

- Divide both sides by 2

                  C = (F - 30)/2
