bx+y=1; 4x-2y=b
Solución
Respuesta rápida
$$b_{1} = -2$$
=
$$-2$$
=
$$x_{1} = \frac{y}{2} - \frac{1}{2}$$
=
$$\frac{y}{2} - \frac{1}{2}$$
=
=
$$-2$$
=
-2
$$x_{1} = \frac{y}{2} - \frac{1}{2}$$
=
$$\frac{y}{2} - \frac{1}{2}$$
=
-0.5 + 0.5*y
$$b_{2} = 2 - 2 y$$
=
$$2 - 2 y$$
=
$$x_{2} = \frac{1}{2}$$
=
$$\frac{1}{2}$$
=
=
$$2 - 2 y$$
=
2 - 2*y
$$x_{2} = \frac{1}{2}$$
=
$$\frac{1}{2}$$
=
0.5
