(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Express the formula for converting Celsius temperatures to Fahrenheit.

2. Relevant equations

C= (F+40)(5/9) - 40

3. The attempt at a solution

C= (F+40)(5/9) - 40

C- 40= (F+40 - 40)(5/9) - 40

(C-40)9/5= F(9/5)(5/9) - 40

(C - 40)9/5 + 40= F - 40 + 40

F= (C - 40)9/5 + 40

Answer: F= (C + 40)9/5 - 40

Could someone please explain to me why the operation signs in the (C + 40) and - 40 are opposite from the solution I came up with?
