Question

Metodo de reduccion: 5x – 3y = 14
6x + 2y = 0

Answer 1

Respuesta:

$x = 1$

$y = - 3$

Explicación paso a paso:

$5x - 3y = 14 \\ 6x + 2y = 0$

$( + 2)5x - 3y = 14 \\ ( + 3)6x + 2y = 0$

$+ 10x - 6y = 28 \\ + 18x + 6y = 0$

$+ 28x = 28 \\ x = \frac{28}{28} \\ x = 1$

$Reemplazando \: x:$

$6x + 2y =0 \\ 6(1) + 2y = 0 \\ 2y = - 6 \\ y = - \frac{6}{2} \\ y = - 3$
