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