Kn7ght. You're hilarious mister. No more out of you tonight or I'll have to punish you.

Jakuza, I'm not in Algebra at the moment so I've yet to learn this. However, I just used some logical thinking and figured out the first one. I'm currently doing the second one, and if I figure it out I'll be sure to give you the answer. Anyway, here is how I did the first one.

Starting problem:

1/C + 1/3C = 2/3
1/C(1/1 + 1/3) = 2/3 Factor out the 1/C (Distributive Property)
(1/1 + 1/3) = 2C/3 Multiply both sides by 'C' to try and isolate 'C'.
3(1/1 + 1/3) = 2C Multiply both sides by '3'
3/1 + 3/3 = 2C Distributive property to simplify
3 + 1 = 2C Simplify
4 = 2C Simplify
2 = C Isolate 'C'


I'll try and get the other one later. Hope I've helped.
