This equation is actually the conversion of Fahrenheit degrees into Celcius. The problem is now asking you to find the conversion equation of Celcius degrees into Fahrenheit. You will see them again in future classes and your life, so it's good to learn and remember them. Here we go:
.
C=%285%2F9%29%28F-32%29
.
We need to isolate F, so first, let's get rid of 5/9 by multiplying its reciprocal on both sides of the equation... its reciprocal is 9/5.
C%289%2F5%29=F-32
Now, let's add 32 to both sides to leave F alone.
C%289%2F5%29%2B32=F
Or you can state it as:
F=C%289%2F5%29%2B32
