Step-by-step explanation:
given
6x - 17 = k ( isolate 6x by adding 17 to both sides )
6x = k + 17 ( divide both sides by 6 )
x = 
The correct answer is Choice A.
Starting with the Fahrenheit Formula, we need to subtract 32 from both sides. Next, we need to multiply both sides by 5/9 to eliminate the fraction 5/9. Doing these two steps will give you the equation in Choice A.
