If #C=4#, #F=39.2#.

You have an equation that takes in #F# values and spits out #C# values.

You want an equation that takes in #C# values and spits out #F# values.

Start with #C=5/9(F-32)#.

Multiply both sides by #9/5# to get #9/5C=F-32#.

Add #32# to both sides to get #9/5C+32=F#.

So #F=9/5C+32#.

So if #C=4#, #F=9/5(4)+32=39.2#.
