22х=44

х=2

Answer 2

Ответ:

$- 4 \times (5 - 2x) + 3 \times (x - 4) = 6 \times (2 - x) - 5x \\ ( - 4) \times 5 + ( -4 )\times ( - 2x) + 3 \times x + 3 \times ( - 4) = 6 \times 2 + 6 \times ( - x) - 5\\ - 20 + 8x + 3x - 12 = 12 - 6x - 5x \\ 8x + 3x + 6x + 5x = 20 + 12 + 12\\ 11x + 11 x = 32 + 12\\ 22x = 44 \\ x = 44 \div 22 \\ x = \boxed{2}$
