In the figure (Figure 1), let C1=5.00μF, C2=7.00μF, C3=9.00μF, and V=36.0V.

I ******* hate electricity , its the most stupidest **** i have ever seen in my life, i truly hope i never have to touch this garbage illogical math ever again.
I cant figure this crap out and im on my last try. I connected c23 = 3.94 micro F, bc 1/7+1/9 ^-1
and then i connected c1 and c23 bc in parrallel to get 8.94 micro F then i figured out Q total is 8.94 micro F * 36v = 321.75 charge. How the **** do i find voltage from this? Q=CV but i cant get this right
Why isnt the charge just v1 = 18 , v2=v3=9?
Update:Clarification, question is
What is the potential difference across each capacitor?
Enter your answers numerically separated by commas.
V1, V2, V3 =
Information and diagram is included as a printscr picture, but what we do know is c1= 5 micro F, c2= 7 micro F and c3 = 9 micro F and V is 36.0 V. How do I find potential difference across each capacitor?

You don't tell us what the question is? It seems you want the charge and voltage on each?
(C's and Q's in µ)
C₂ & C₃ is series equal 7•9/16 = 3.94 µF
Q for both = 3.94 x36 = 142 µC
C₂ & C₃ have the same charge, rule for series caps
V₂ = Q₂/C₂ = 142/7 = 20.3 volts
V₃ = Q₃/C₃ = 142/9 = 15.8 volts
and they add to 36 volts, within accepted error
Q₁ = C₁V₁ = 5x36 = 180 µC

"c1 and c23" no need to do this
"How do i find voltage" C₁ has the battery across it
the other two, see above.
"Why isnt the charge just v1 = 18 , v2=v3=9" ?? charges is NOT voltage
and V₁ is obviously 36 volts. and V₂+V₃ = 36 volts also. Just look at the connections.
Without answering your question I want to make a different comment.
I can remember learning to play golf. All I did was to hit the ground and the ball went nowhere. I didn't enjoy that.
Learning to ride a bike I fell off. I didn't enjoy that.
Learning to play the flute. Awkward, uncomfortable and made terrible squeaks. I didn't enjoy that either.
The list goes on and on. You don't enjoy anything until you get some basic points first.
Now if you simply abandon everything that you don't already know, you would have given up learning to speak, to crawl, and wouldn't be toilet trained either.
When you were young you persisted with difficult things and mastered them.
So why would you let yourself become lesser now?
