Question

F=9/5C+32 Find C when F = 53.6.

Answer 1

You have F, which is 53.6, so to find C we will plug in 53.6 for F and evaluate for C:
\[53.6=(9/5)C + 32\]You now need to get C by itself. You can start by subtracting 32 from both sides:
\[21.6=(9/5)C\]Now, all you need to do is multiply both sides by 5/9 and you'll have isolated C.

Answer 2

f=9/5c+32 now f=53.6
53.6=9/5c+32
53.6-32=9/5c
21.6=9/5c
now cross multiply
5c=9/53.6
to make it easy multiply and divide it by 10
5c=90/536
5c=0.167
c=0.33
you can take 90/167 as many desimals you want depending upon answer
