16x - [3x - (6 - 9x)] = 30x + [ - (3x + 2 - (x + 3)]?

16x - [3x - (6 - 9x)] = 30x + [ - (3x + 2 - (x + 3)].

En resumen

16x - [3x - (6 - 9x)] = 30x + [ - (3x + 2 - (x + 3))] 16x - [3x - 6 + 9x] = 30x + [ - (3x + 2 - x - 3)] 16x - [12x - 6] = 30x + [ - (2x - 1)] 16x - 12x + 6 = 30x + [ - 2x + 1] 4x + 6 = 30 - 2x + 1 4x + 6 = 31 - 2x 4x - 2x = 31 - 6 2x = 25 x = 25 / 2 = 12, 5 Espero que te ayude.

16x - [3x - (6 - 9x)] = 30x + [ - (3x + 2 - (x + 3))]

16x - [3x - 6 + 9x] = 30x + [ - (3x + 2 - x - 3)]

16x - [12x - 6] = 30x + [ - (2x - 1)]

16x - 12x + 6 = 30x + [ - 2x + 1]

4x + 6 = 30 - 2x + 1

4x + 6 = 31 - 2x

4x - 2x = 31 - 6

2x = 25

x = 25 / 2 = 12, 5

Espero que te ayude.
