Question

6x-3y=27 x+3y=8 metodo de igualacion quien responda bien doy corona ​

Answer 1

Explicación paso a paso:

$6x - 3y = 27 \\ 6x = 27 + 3y \\ x = \frac{27 + 3y}{6} \\ x + 3y = 8 \\ x = 8 - 3y$

$8 - 3y = \frac{27 + 3y}{6} \\ 48 - 18y = 27 + 3y \\ - 27 + 48 = 3y + 18y \\ 21 = 21y \\ y = \frac{21}{21} = 1 \\ y = 1$

$x = 8 - 3y = 8 - 3 \times 1 = 8 - 3 = 5 \\ x = 5$

$6x - 3y = 6 \times 5 - 3 \times 1 = 30 - 3 = 27$

$x + 3y = 5 + 3 \times 1 = 5 + 3 = 8$
