Consider the following system of equations in three real variables $$x1, x2$$ and $$x3$$ :

$$2x1 - x2 + 3x3 = 1$$

$$3x1 + 2x2 + 5x3 = 2$$

$$ - x1 + 4x2 + x3 = 3$$

This system of equations has

$$2x1 - x2 + 3x3 = 1$$

$$3x1 + 2x2 + 5x3 = 2$$

$$ - x1 + 4x2 + x3 = 3$$

This system of equations has
