Hi
The other paramaters are known?
beta, K, P0..... and q?

There is no explicit solution. You could get a numerical solution if you know the other variables.

the other variables have their own equations

"the other variables have their own equations"
Do they depend on P?

Example
clear,clc
beta = 0.5;
kH = 1;
P0 = 1;
qm = 2;
kS = 0.01;
n = 2;
qx = 1;
func = @(P) qx-(beta*kH*(P/P0)+(1-beta)*qm*(kS*P/P0)^(1/n)/(1+(kS*P/P0)^(1/n)));
result = fzero(func,1)
result = 1.7654
Just replace the actual values of all the constants and you're good to go.
