K = (F - 32) + 273.15
To cancel out the 5/9, you can either multiply everything by the denominator and divide it down, or multiply everything by the reciprocal of the fraction (. Multiplying by the reciprocal is definitely easier if you can use a calculator:
K = (F - 32) + 491.67
Subtract 491.67 from both sides:
K - 491.67 = F - 32
Finish off by adding 32 to both sides:
K - 459.67 = F
Therefore, F = K - 459.67.
Hope this helps! :)
