Question

2x + 2y =160
x= 3y
sistema de ecuaciones lineales​

Answer 1

Respuesta:

Y= 21.71

X= 16.65

Explicación paso a paso:

despejes:

x= 160-2y.

¯¯¯¯4¯¯¯¯¯¯

X= 3y

Igualar despejes:

169-2y = 3y

¯¯¯4¯¯¯¯

160-2y = 4(3y)

152y = 7y

Y= - 152/-7

Y= 21.71

X=160-2 (21.71) 160-43.42 116.52

¯¯¯¯¯¯¯7¯¯¯¯¯¯¯ = ¯¯¯¯¯7¯¯¯¯¯¯ = ¯¯¯¯7¯¯¯¯ = 16.65

X=16.65
