Question

resolver el método de igualación

3x-4y=-6
2x+4y=16
​

Answer 1

Explicación paso a paso:

$3x - 4y = - 6 \\ 3x = - 6 + 4y \\ x = \frac{ - 6 + 4y}{3}$

$2x + 4y = 16 \\ 2x = 16 - 4y \\ x = \frac{16 - 4y}{2}$

$\frac{ - 6 + 4y}{3} = \frac{16 - 4y}{2} \\ - 12 + 8y = 48 - 12y \\ - 48 - 12 = - 12y - 8y \\ - 60 = - 20y \\ 20y = 60 \\ y = \frac{60}{20} = 3$

$3x - 4y = - 6 \\ 3x - 4 \times 3 = - 6 \\ 3x - 12 = - 6 \\ 3x = - 6 + 12 \\ 3x = 6 \\ x = \frac{6}{3} = 2$

3*2-4*3=-6

2*2+4*3=16
