Hmm I don't think the first equation in your answer is correct. A counterexample is $A = [1 -1; 0 -1]$ -- there is no constant $c$ satisfying your identity.

comment Real solutions for systems of monomial equations
@OlegEroshkin My mistake, just fixed the question to specify that the $a_{ij}$ are non-negative integers, so $x_i^{a_{ij}}$ is well-defined when $x_i$ is negative. I do want to be able to find solutions when $c_i$ or $x_i$ is non-positive.
