En resumen

- (4x - ( - 2 - 3x - 6)) = 4 - ( - x + 2x - 1) - (4x + 2 + 3x + 6) = 4 + x - 2x + 1 - 4x - 2 - 3x - 6 = 5 - x - 7x - 8 = 5 - x - 7x + x = 5 + 8 - 6x = 13 x = - 13 / 6.

- (4x - ( - 2 - 3x - 6)) = 4 - ( - x + 2x - 1) - (4x + 2 + 3x + 6) = 4 + x - 2x + 1 - 4x - 2 - 3x - 6 = 5 - x - 7x - 8 = 5 - x - 7x + x = 5 + 8 - 6x = 13

x = - 13 / 6.
