Hey there!

I know, I know... you don’t have to tell me, I’ve had my share of these long equations that I’m left to just not understand.
Now I know how to solve. I can show you.

What we want to do first is divide both sides by the numeric factor on the left side, then solve. Now we can calculate and find out what C equals!

C= 9/2

^^^ there’s the answer! Happy studying.
