Question

3x+2y-7=0;2x-3y+4=0​

Answer 1

Respuesta:

y = 2 x = 1

Explicación paso a paso:

$3x + 2y - 7 = 0 \\ 3x + 2y = 7 \\ 3x = 7 - 2y \\ x = \frac{7 - 2y}{3}$

$2x - 3y + 4 = 0 \\ 3y - 2x = 4 \\ \frac{3y - 4}{2} = x$

$\frac{7 - 2y}{3} = \frac{3y - 4}{2} \\ 14 - 4y = 9y - 12 \\ 26 = 13y \\ 2 = y$

$x = \frac{3y - 4}{2} \\ x = \frac{3(2) - 4}{2} \\ x = \frac{2}{2} \\ x = 1$
