Answer:

$F = 32 + \frac{9}{5}(K - 273)$

Step-by-step explanation:

Given

$K = \frac{5}{9}(F - 32) + 273$

Required

Solve for F

$K = \frac{5}{9}(F - 32) + 273$

Subtract 273 from both sides

$K - 273= \frac{5}{9}(F - 32) + 273 - 273$

$K - 273= \frac{5}{9}(F - 32)$

Multiply through by $\frac{9}{5}$

$\frac{9}{5} *(K - 273)= \frac{9}{5} * \frac{5}{9}(F - 32)$

$\frac{9}{5}(K - 273)= F - 32$

Add 32 to both sides

$32 + \frac{9}{5}(K - 273)= F - 32 + 32$

$32 + \frac{9}{5}(K - 273)= F$

$F = 32 + \frac{9}{5}(K - 273)$
