\frac{9}{5}c=68-32
Subtract 32 from both sides.
\frac{9}{5}c=36
Subtract 32 from 68 to get 36.
c=36\times \frac{5}{9}
Multiply both sides by \frac{5}{9}, the reciprocal of \frac{9}{5}.
c=\frac{36\times 5}{9}
Express 36\times \frac{5}{9} as a single fraction.
c=\frac{180}{9}
Multiply 36 and 5 to get 180.
c=20
Divide 180 by 9 to get 20.
