6× - (2× + 1) = - { - 5× + [ - ( - 2× - 1)]}?

6× - (2× + 1) = - { - 5× + [ - ( - 2× - 1)]}.

En resumen

6× - (2× + 1) = - { - 5× + [ - ( - 2× - 1)]} 6× - 2× - 1 = - { - 5× + [ + 2× + 1]} 6× - 2× - 1 = - { - 5× + 2× + 1} 4× - 1 = - { - 3x + 1} 4× - 1 = + 3× - 1 4x - 3x = - 1 + 1 x = 0.

6× - (2× + 1) = - { - 5× + [ - ( - 2× - 1)]}

6× - 2× - 1 = - { - 5× + [ + 2× + 1]}

6× - 2× - 1 = - { - 5× + 2× + 1}

4× - 1 = - { - 3x + 1}

4× - 1 = + 3× - 1

4x - 3x = - 1 + 1

x = 0.
