Question

usar el metodo de reduccion

3x-4y+23 =0

6y+11x=0

Answer 1

Respuesta:

3x-4y+23 =0

6y+11x=0

3x - 4y = - 23

11x+ 6y = 0

(3x - 4y = - 23) * 6

(11x+ 6y = 0) * 4

18x - 24y = - 138

44x + 24y = 0

----------------------

62x        = -138

$x = -\frac{138}{62} \\\\x = - \frac{69}{31}$

Reemplazamos la x

$3(-\frac{69}{31} - 4y = -23\\\\y = \frac{253}{62}$
