ax+by=7; bx+cy=5

Ha introducido [src]

a*x + b*y = 7

$$a x + b y = 7$$

b*x + c*y = 5

$$b x + c y = 5$$

b*x + c*y = 5

Respuesta rápida

$$a_{1} = \frac{c y^{2} + 7 x - 5 y}{x^{2}}$$
=
$$\frac{c y^{2} + 7 x - 5 y}{x^{2}}$$
=

(7*x - 5*y + c*y^2)/x^2

$$b_{1} = - \frac{c y - 5}{x}$$
=
$$\frac{- c y + 5}{x}$$
=

-(-5 + c*y)/x
