You have entered [src]

y - 7*x = 3

$$- 7 x + y = 3$$

 2            2     
y  - 6*x*y - x  = -9

$$- x^{2} + \left(- 6 x y + y^{2}\right) = -9$$

-x^2 - 6*x*y + y^2 = -9

Rapid solution

=
$$-3$$
=

-3

$$y_{1} = -18$$
=
$$-18$$
=

-18

$$x_{2} = -1$$

Numerical answer [src]

x1 = -3.0
y1 = -18.0

x2 = -1.0
y2 = -4.0

x2 = -1.0
y2 = -4.0
