срочно​

Answer 1

Объяснение:

$6 \times (2.3x - 1) - 3.5x + 0.7x = 0.5(x - 14) \\ 13.8x - 6 - 3.5x + 0.7x = 0.5(x - 14) \\ 10.3x - 6 + 0.7x = 0.5(x - 14) \\ 11x - 6 = 0.5(x - 14) \\ 11 x - 6 = 0.5x - 7 \\ 11x - 6 - 0.5x = - 7 \\ 10.5x - 6 = - 7 \\ 10.5x = - 7 + 6 \\ 10.5x = - 1 \\ x = -10 \div 105 \\ x = - \frac{2}{21}$
