Respuesta:

a) = -1

b) = 41

c) = 206

Explicación paso a paso:

(5-3)×[(-6)+(5+1)-(-5)]-[(5+6)-(-7+9)-(-2)]

$=2\times \:\left[\left(-6\right)+\left(5+1\right)-\left(-5\right)\right]-\left[\left(5+6\right)-\left(-7+9\right)-\left(-2\right)\right]\\=2\times \:5-\left[\left(5+6\right)-\left(-7+9\right)-\left(-2\right)\right]\\=2\times \:5-11\\=10-11\\=-1$

(-5+7-3)-[(-5+13)+(-3-1)+(4-5)+9×(-5)]

$=-1-\left[\left(-5+13\right)+\left(-3-1\right)+\left(4-5\right)+9\times \left(-5\right)\right]\\=-1-\left(-42\right)\\=41$

(-7-8)[(-4)+(-4+2)-(+9)]-[(3+10)-(-18+9)+(-3)]​

$=-15\left[\left(-4\right)+\left(-4+2\right)-\left(9\right)\right]-\left[\left(3+10\right)-\left(-18+9\right)+\left(-3\right)\right]\\=-15\left(-15\right)-\left[\left(3+10\right)-\left(-18+9\right)+\left(-3\right)\right]\\=-15\left(-15\right)-19\\=225-19\\=206$
