Question

[y — 2х = 1, 5,
[12x – 6y = - 9;​

Answer 1

Ответ:

$x = 0 \\ y = 1.5$

Пошаговое объяснение:

$y - 2x = 1.5 \\ 12x - 6y = - 9$

$1) y - 2x = 1.5 \\ y = 1.5 + 2x$

$2)12x - 6 \times (1.5 + 2x) = - 9 \\ 12x - 9 - 12x = - 9 \\ 0x = 0 \\ x = 0$

$3)y - 2x = 1.5 \\ y - 2 \times 0 = 1.5 \\ y = 1.5$
