Hey!

I guess these problems that bother me are rather simple to you. Hopefully I can get these fundamental algebraic problems out of my way, with a little bit of help by you.

First of, I'm solving a problem concerning Edgeworths box ( Yea I know, completely worthless in real life).

The thing is the following, I have the following equation that I'm supposed to solve for Y1:

(3Y1/X1) = (Ny - Y1) / (Nx - X1)

The answer is supposed to be: Y1(X1) = NyX1/(3Nx-2X1)

I can see NyX1, but where did Y1 go?

I can see 3Nx, but where did 2X1 come from?

Secondly I have the following problem in a MRS equation;

Q(L,K) = 12L^(1/3)K^(1/2) = Q

L = 4,5K

Solve for K.

The answer is supposed to be:K = Q^(6/5)/36

I'm thankful for answers.
