Question

2x + y=-10
x-3y=2
Eliminacion (suma y resta)

Answer 1

Respuesta

Explicación paso a paso:

$y = - 10 - 2x$

$y = \frac{2 - x}{3}$

$y = 6 - 3x$

suma

$y = - 4 - 5x$

Answer 2

Respuesta:

2x + y=-10

Operaciones:

2 x + y+ 10 = 0

( 2 ) ⋅ x + ( y+ 10 ) = 0

x =- ( y+ 10 )2

x = -1/2y- 5

Resultado final:

x = -1/2y- 5

x-3y=2

Operaciones:

x - 3 y- 2 = 0

( 1 ) ⋅ x + ( - 3 y- 2 ) = 0

x =- ( - 3 y- 2 )1

x = 3 y+ 2

Resultado final:

x = 3 y+ 2
