a)
F = [tex]\frac{5}{9}[/tex](K - 273.15) + 32
- 32 - 32
F - 32 = [tex]\frac{5}{9}[/tex](K - 273.15)
[tex]\frac{9}{5}[/tex](F - 32) = [tex]\frac{9}{5}[/tex][[tex]\frac{5}{9}[/tex](K - 273.15)]
[tex]\frac{9}{5}[/tex](F - 32) = K - 273.15
[tex]\frac{9}{5}F[/tex] - [tex]\frac{9(-32)}{5}[/tex] = K - 273.15
[tex]\frac{9}{5}F[/tex] - 57.6 = K - 273.15
+ 273.15 + 273.15
[tex]\frac{9}{5}F[/tex] - 215.55 = K
b)
[tex]\frac{9}{5}(180)[/tex] - 215.55 = K
324 - 215.55 = K
108.45 = K
