  Hi @spaceblastxy1428, What a nice question! Good observation! It is correct that over all real numbers there is only one solution, and it is \((0, 0, 0).\) However, the Challenge Question didn't mention that there should be a unique solution over all real numbers, right? So what about complex numbers? All in all, there do indeed exist solutions in complex numbers, and they are not unique Hopefully your task was not to find a single solution, but to find a set of equations that has a unique solution. And the idea behind this problem wasn't to check whether you can solve the system of equations or not, but to check your understanding of the core concept of the systems of equations: in order to have a unique solution with \(n\) variables, you have to have at least \(n\) equations. That's all
