comment All measures $\alpha,\beta$ on $[0,1]$ satisfying certain moment conditions
@Robert Israel, thanks for the answer. The question, anyway, came exactly from this problem of signed measures. If I am not wrong, assuming that $\gamma, \gamma^\prime$ are solutions then also $2\gamma-\gamma^\prime$ is another solution (and similarly for their affine hull). But is there a way to write all these solutions in a "better" form?
