Question

РЕШИТЕ ПОЖАЛУЙСТА!!!!!!!!​

Answer 1

Пошаговое объяснение:

$- 3x = 43 \\ x = 43 \div ( - 3) \\ x = - 14.3(3)$

$- 2x - 9 = 31 \\ - 2x = 31 + 9 \\ - 2x = 40 \\ x = 40 \div ( - 2) \\ x = - 10$

$5 x + 22 = 3x - 45 \\ 5x - 3x = - 45 - 22 \\ 2x = - 67 \\ x = - 67 \div 2 \\ x = - 33.5$

$2(x + 3) = - 3(x - 4) \\ 2 \times x + 2 \times 3 = - 3 \times x - 3 \times ( - 4) \\ 2x + 6 = - 3x + 12 \\ 2x + 3x = 12 - 6 \\ 5x = 6 \\ x = 6 \div 5 \\ x = 1.2$

Последнее не знаю, сори :-/
