Web$\begingroup$ @Griezy: Since you have a linear system of three equations, you should just analyze the coefficient matrix, C={{a,1,a},{1,a,1},{1,0,a}} in your example. For real solution, a should not be equal to 1 nor -1 , in which case you will end up with indeterminacy. for all other values of coefficients there is a real solution. $\endgroup$ WebCheck that the ordered triple is a solution to all three original equations.
