Question

Sistema de ecuación lineal

6x=15y−2

−2x=−18y+5

Answer 1

Respuesta:

x = -11/78

y = 1/13

Explicación paso a paso:

metodo de igualacion:

6x=15y−2

−2x=−18y+5

despejamos x

x = (15y - 2)/6

x = (-18y + 5)/-2

ahora igualamos

(15y - 2)/6 = (-18y + 5)/-2

(15y - 2)-2 = (-18y + 5)6

-30y + 4 = -108y+ 30

-30y + 108y = 30 - 4

78y = 26

y = 26/78 simplificando seria : 1/13

reemplazando:

6x=15y−2

6x = 15(1/13) - 2

6x = 15/13 - 2

6x = -11/13

x = -11/78
