k*x - 2*y = -2
$$k x - 2 y = -2$$
8*x + 5*y = 18
$$8 x + 5 y = 18$$
8*x + 5*y = 18
Respuesta rápida
$$k_{1} = - \frac{16 \left(y - 1\right)}{5 y - 18}$$
=
$$\frac{16 \left(1 - y\right)}{5 y - 18}$$
=
$$x_{1} = - \frac{5 y - 18}{8}$$
=
$$\frac{9}{4} - \frac{5 y}{8}$$
=
=
$$\frac{16 \left(1 - y\right)}{5 y - 18}$$
=
-16*(-1 + y)/(-18 + 5*y)
$$x_{1} = - \frac{5 y - 18}{8}$$
=
$$\frac{9}{4} - \frac{5 y}{8}$$
=
2.25 - 0.625*y
