Answer

C = $\frac{5}{9}$F - $\frac{160}{9}$

Work Step by Step

Using the properties of equality we obtain: $ F =\frac{9}{5}C + 32$ $ F - 32 = \frac{9}{5}C + 32 - 32$ Subtract 32 from both sides $ F - 32 = \frac{9}{5}C$ $F \times \frac{5}{9} - 32 \times \frac{5}{9} =\frac{9}{5}C \times \frac{5}{9}$ Muliply both sides by $\frac{5}{9}$ C = $\frac{5}{9}$F - $\frac{160}{9}$
