Question

The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F:

F = 9 over 5C + 32

Which of the following formulas correctly solves for C?

C = 5F − 32 over 9
C = 5 F over 9 − 32
C = 9 over 5(F − 32)
C = 5 over 9(F − 32)

Answer 1

F = (9/5)C + 32

since we have + 32, you can subtract 32 from both sides

then, to eliminate that 9/5 fraction, multiply both sides by 5/9
