Помогите!!!!!!!!!!ПЖ​

Answer 1

Ответ:

Пошаговое объяснение:

12+4x-12-2x=5-3x+9

4x-2x+3x=5+9-12+12

5x=14

x=2.8

Answer 2

$12 + 4(x - 3) - 2x = (5 - 3x) + 9 \\ 12 + 4x - 12 - 2x = 5 - 3x + 9 \\ 2x = 14 - 3x \\ 2x + 3x = 14 \\ 5x = 14 \\ x = \frac{14}{5} \\ x = \frac{14}{5}$

или

$x = 2 \frac{4}{5} \\ x = 2.8$
