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.
