Question

ecuacion metodo igualacio 5x-y=3 -2x+4y=-12

Answer 1

Respuesta:

$5x - y = 3 - 2x + 4y = 12$

$5 \times - y = 12$

$3 - 2 \times + 4y = 12$

$- 2x + 4y = 9$

$20 \times - 4y = 48$

$- 2 x + 4y = 9$

$18x = 57$

$x = \frac{19}{6}$

$- 2x \frac{19}{6} + 4y = 9$

$y = \frac{23}{6}$

$(x \: y) = ( \frac{19}{6} \: \frac{23}{6} )$

$5 \times \frac{19}{6} - \frac{23}{6} = 3 - 2 \times \frac{19}{6} + 4 \times \frac{23}{6} = 12$

$12 = 12 = 12$

$respuesta \\ (x \: y) = ( \frac{19}{6} \: \: \frac{23}{6}$)
