Explicit solutions for a system of equations. [Struct]

I tried to solve a system of three equations for variable k,n and c as below:

eqn1= z*a*k^(a-1)*n^(1-a)-d==h
eqn2= z*k^a*n^(1-a)-d*k==c
eqn3= r*c/(1-n)==z*(1-a)*k^a*n^(-a)

The problem is that the result shows it is a "struct," which I do not know how to see the explicit equations for k, n, and c. I can solve it by my handwriting calculation as follows:

c is just inserting k and n to the equation 2:

z*k^a*n^(1-a)-d*k==c.

What is wrong with my code, and how can I see the solutions explicitly? It happens every time I try to use Matlab, so I just use my hand calculation every time.

Below are codes and results:

clc
clear
syms z a k n d h c r
assume(z>0);
assume(a>0 & 1>a);
assume(n>0 & 1>n);
assume(k>0);
assume(c>0);
assume(d>0 & 1>d);
assume(h>0);
assume(r>0 & 1>r);
eqn1= z*a*k^(a-1)*n^(1-a)-d==h
eqn2= z*k^a*n^(1-a)-d*k==c
eqn3= r*c/(1-n)==z*(1-a)*k^a*n^(-a)
sol=solve([eqn1,eqn2,eqn3],[k,n,c], 'IgnoreAnalyticConstraints',1)

Note that the names of the fields of your struct array are exactly the names of the variables for which you told solve to solve. So the solution for k is sol.k and so on and so forth. If you type sol.k you'll be able to see those solutions.

This is what I got. How can I see u, y, and x?

>> sol.k

    ans =

    x

    >> sol.n

    ans =

    y

    >> sol.c

    ans =

    u
