Answer 2

Respuesta:

3

Explicación paso a paso:

$\left[\left(-12\right)-\left(-20\right)\right]-\left[\left(6\right)+\left(5-9\right)-\left(8-11\right)\right]$

----------------------------------------------------------

$\left(-12\right)-\left(-20\right)\\=\left(-12\right)+20\\=8$

----------------------------------------------------------

$=8-\left[\left(6\right)+\left(5-9\right)-\left(8-11\right)\right]$

----------------------------------------------------------

$\left(6\right)+\left(5-9\right)-\left(8-11\right)\\=\left(6\right)-4-\left(8-11\right)\\=\left(6\right)-4-\left(-3\right)\\=5$

----------------------------------------------------------

$=8-5\\=3$
