    Are you sure your third equation is not
    9a+ 16b+ 25c +36d +49e = -3 ?

    Then it would fall into a certain pattern with the others.
    16a +25b +36c +49d +64e = +2

    In general, your first three equations in five unknowns have an infinite number of possible solutions, so that the fourth equation cannot be solved uniquely
