ANSWER
C=K-273
EXPLANATION
The given formula is: K=C+273
We need to solve this formula for the variable, C.
This means that we need to isolate the variable C on one side of the equation, leaving any other terms on the other side of the equation.
We subtract 273 from both sides of the equation to obtain,
K-273=C
This is the same as
C=C-273
