Math help, screenshot in comments.
aka: The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F: F = 9 over 5C + 32 Which of the following formulas correctly solves for C? C = 5F − 32 over 9 C = 5 F over 9 − 32 C = 9 over 5(F − 32) C = 5 over 9(F − 32)

if you go on mathway.com and type in your equation is should help you, also symolab.com is another awesome website for that and it shows you work to go along with it if you need the work for the question
\[\large\rm F=\frac95C+32\]If you want to isolate the C, you need to "undo" all of the stuff being applied to the side containing the C. You're trying to get all of that stuff off of it. Start with the simplest operation first. Since 32 is being added to C, subtract 32 from each side, \[\large\rm F-32=\frac95C\]
To "undo" a fraction, we can multiply each side by it's reciprocal, it's flip.\[\large\rm \frac59\left(F-32\right)=\frac59\cdot\frac95C\]
Which leads to some nice cancellations,\[\large\rm \frac59\left(F-32\right)=\frac{\cancel5}{\color{blue}{\cancel{\color{black}{9}}}}\cdot\frac{\color{blue}{\cancel{\color{black}{9}}}}{\cancel5}C\]
\[\large\rm \frac59\left(F-32\right)=C\]
