C=5/9 (F-32), solve for F

c=5/9 (f-32) can also be written as c = 5 (f - 32) / 9.

Multiply each side by 9.

That gives us 9c = 5 (f - 32).

Apply distributive rule on the right side.

9c = 5f - 160

Add 160 to the left side.

9c + 160 = 5f

Lastly, divide both sides 5.

(9c + 160) / 5 = f

Your answer is

F = 32 + 9C/5
