Question

solución de sistema
2x+4y=4
3x-2y=2​

Answer 1

Explicación paso a paso:

$2x + 4y = 4 \\ 3x - 2y = 2 \: \: ( \times 2) \\ \\ 6x - 4y = 4 \\ 2x + 4y = 4 \\ 8x = 8 \\ x = \frac{8}{8} = 1 \\ \\ 2x + 4y = 4 \\ \\ 3 \times 1 - 2y = 2$

$3 - 2y = 2 \\ - 2y = 2 - 3 \\ - 2y = - 1 \\ 2y = 1 \\ y = \frac{1}{2}$

$2x + 4y = 4 \\ 2 \times 1 + 4 \times \frac{1}{2} = 2 \times \frac{4}{2} = 2 \times 2 = 4$

$3x - 2y = 2 \\ 3 \times 1 - 2 \times \frac{1}{2} = 3 - \frac{2}{2} = 3 - 1 = 2$
