2.= 7

Explicación paso a paso:

$-2-\left[-6+\left(-4\right)\div \left(-2\right)-\left(7-5\right)\right]\\\\=-2-\left(-6\right)\\\\=4$

2.

$1-\left[-4+\left(-10\right)\div \left(-5\right)\right]+\left[3+\left(-9\right)\div \left(-9\right)\right]\\\\=1-\left(-2\right)+\left[3+\left(-9\right)\div \left(-9\right)\right]\\\\=1-\left(-2\right)+4\\\\=7$
