Quadratic Simultaneous Equations with Four Variables












0














I have the following equations, where $a$ to $j$ are real constants, and $w, x, y$ and $z$ are values to be solved for:



$$awx - bwy - cxy + dy^2 = 0$$
$$gyz - bwy - fwz + ew^2= 0$$
$$gyz - ixz - cxy + hx^2= 0$$
$$awx - ixz - fwz + jz^2 = 0$$



I have tried some elimination and substitution but that didn't seem to lead anywhere. Where should I go from here?
