Explicación paso a paso:
x – [ – 2x – (x – 1)] = x + (– 3x + 11)
x – [ – 2x – x + 1] = x – 3x + 11
x + 2x + x – 1 = x – 3x + 11
4x – 1 = –2x + 11
4x + 2x = 11 + 1
6x = 12
x = 12/6
x = 2
Comprobación:
x – [ – 2x – (x – 1)] = 6 + (– 3x + 11)
2 – [ – 2.2 – (2 – 1)] = 2 + (– 3.2 + 11)
2 – [ – 4 – 1] = 6 + (–6 + 11)
6 – [–5] = 6 + 5
6 + 5 = 6 + 5
11 = 11
