Given the formula, solve for the indicated variable. F=9/5c + 32 for c

SVEN [57.7K]

F = $\frac{9}{5}$ c + 32 Subtract 32 from both sides
F - 32 = $\frac{9}{5}$ c Mutliply both sides by $\frac{5}{9}$ to cancel out the fraction
 $\frac{5}{9}$ F - 17 $\frac{7}{9}$ = c Switch the sides to make it easier to read
c = $\frac{5}{9}$ F - 17 $\frac{7}{9}$
