70\times \frac{9}{5}=F-32
Multiply both sides by \frac{9}{5}, the reciprocal of \frac{5}{9}.
\frac{70\times 9}{5}=F-32
Express 70\times \frac{9}{5} as a single fraction.
\frac{630}{5}=F-32
Multiply 70 and 9 to get 630.
126=F-32
Divide 630 by 5 to get 126.
F-32=126
Swap sides so that all variable terms are on the left hand side.
F=126+32
Add 32 to both sides.
F=158
Add 126 and 32 to get 158.
