x+ay=1; ax+y=a

Ha introducido [src]

x + a*y = 1

$$a y + x = 1$$

a*x + y = a

$$a x + y = a$$

a*x + y = a

Respuesta rápida

$$a_{1} = -1$$
=
$$-1$$
=

-1

$$x_{1} = y + 1$$
=
$$y + 1$$
=

1 + y

$$a_{2} = 1$$
=
$$1$$
=

$$x_{2} = 1 - y$$
=
$$1 - y$$
=

1 - y

$$x_{3} = 1$$
=
$$1$$
=

$$y_{3} = 0$$
=
$$0$$
