Question

F = 1.8C + 32 what is c

Answer 1

Step-by-step explanation:

right.

and therefore c is in this case the name of the variable in the equation (or function).

add on.

ah, do you mean (and does this strange problem description mean) that you want the reverse formula : to get C out of F ?

in that case

F = 1.8c + 32 = 9/5 × c + 32

F - 32 = 9/5 × c

5/9 × (F - 32) = c

or

c = 5/9 × (F - 32)

that's it.
