Question: Simplify solution to system of equations

Hello

I have an 8x8 sytem of equations where I can easily solve the first 2 equations by hand. If I solve the full system in Maple it gives me some ugly expressions and I would like to simplify it. I know that, at least some of it, can be simplified since I have solved two equations by hand. It is easy to show that N_M=(W_M/(B*K_A^(1-B)))^(1/(B-1)) and X_N=(W_M/(B*K_A^(1-B)))^(B/(B-1))*K_M^(1-B), but Maple gives me some result with logarithms.

Can anyone help me solve this system of equations and get some nice solutions, if at all possible?

Thank you!
