Answer 2

Respuesta:

$2x - 6y = - 2 \: \: \: ( \times - 4) \\ - 8x + 24y = 8 \\ 8x + 3y = 12 \\ 27y = 20 \\ y = \frac{20}{27}$

Explicación paso a paso:

$x = \frac{ - 2 + 6y}{2} = \frac{ - 2 + 6 \times \frac{20}{27} }{2} \\ = \frac{ \frac{ - 54}{27} + \frac{120}{27} }{2} = \\ \\ = \frac{ \frac{66}{27} }{2} = \frac{66}{27} \times \frac{1}{2} = \frac{66}{54} = \frac{33}{27} \\ x = \frac{33}{27}$

$2 \times \frac{33}{27} - 6 \frac{20}{27} = \\ \frac{66}{27} - \frac{120}{27} = \frac{ - 54}{27} = - 2$

$8 \times \frac{33}{27} + 3 \times \frac{20}{27} = \frac{264}{27} + \frac{60}{27} = \\ \frac{324}{27} = 12$
