2x - [3a + 2( - 4x + 3) - 3a - x] =?
2x - [3a + 2( - 4x + 3) - 3a - x] =.
2x - [3a + 2( - 4x + 3) - 3a - x] =.
En resumen
= 2x - [3a + 2( - 4x + 3) - 3a - x] = 2x - [3a - 8X + 6 - 3a - x] = 2x - [ - 9X + 6] = 2x + 9X - 6] = 11X - 6.
= 2x - [3a + 2( - 4x + 3) - 3a - x] = 2x - [3a - 8X + 6 - 3a - x] = 2x - [ - 9X + 6] = 2x + 9X - 6] = 11X - 6.
2x - [3a + 2( - 4x + 3) - 3a - x]
2x - [3a - 8x + 6 - 3a - x]
2x - [ - 9x + 6]
2x + 9x - 6
11x - 6.
