Question

despejar Y:

X+6Y= -1
2 x +2 Y = -7​

Answer 1

Respuesta:

x = -4 y = 1/2

Explicación paso a paso:

X+6Y= -1 => x = -1 - 6y

2 x +2 Y = -7 => x = -7 - 2y/2

-1 - 6y = -7 - 2y/2

-2 - 12y = -7 - 2y

5 = 10y => y = 1/2 x = -4

Comprobación:

-4 + 6(1/2) = -1

-4 + 3 = -1 => -1 = -1

2(-4) + 2(1/2) = -7

-8 + 1 = -7 => -7 = -7

RPTA: la y es 1/2
