Пошаговое объяснение:

$- 3x + 2 = 5x - 15 \\ - 8x = - 17 \\ x = \frac{17}{8}$

$2x + 7 = - 19 \\ 2x = - 26 \\ x = - 13$

$- 4x + 7 = 5x + 1 \\ - 9x = - 6 \\ x = \frac{6}{9} = \frac{2}{3}$

$4x + 3 = - 2x - 5 \\ 6x = - 8 \\ x = - \frac{ 8}{6} = - \frac{ 4}{3}$

$2x - (4 - 5x) = - (6 - 3x) \\ 2x - 4 + 5x = - 6 + 3x \\ 4x = - 2 \\ x = - \frac{ 2}{4} = - \frac{1}{2}$
