Question

To change Fahrenheit temperatures to Celsius temperatures, you can use the formula C = 5959(F – 32). Which answer is the best first step to solve the equation for F?

Answer 1

-We cannot add 32 to both sides yet since it is attached to F within the parenthesis. 
-It is not subtract F from both sides since the F is already separated on the opposite side from C. 
-We cannot divide F because it is still within the parenthesis. 
I assume by 5959 you mean 5/9 and by 9595 you mean 9/5. So by multiplying 
each side by 9/5, you are able to isolate the parenthesis (F-32). 
9/5C= F-32
If you wanted to solve the equation all the way through, you would just add 32 to each side. 

Answer 2

Multiply both sides by 9/5
