Answer 1

Bien Veamos:

$\boxed {\displaystyle \mathbb {PROCEDIMIENTO:}}$

$\left(12\right)-\left(-12\right)+4+6\left(-9\right)+\left(15\right)-\left(-9\right)\\\\=\left(12\right)-\left(-12\right)+4-54+\left(15\right)-\left(-9\right)\\\\=\left(12\right)+12+4-54+\left(15\right)-\left(-9\right)\\\\=24+4-54+\left(15\right)-\left(-9\right)\\\\=28-54+\left(15\right)-\left(-9\right)\\\\=-26+\left(15\right)-\left(-9\right)\\\\=-11-\left(-9\right)\\\\=-11+9\\\\=-2$

Answer 2

Respuesta:

(+12)-(-12)+4+6(-9)+(+15)-(-9)​ = -2

(+12)-(-12)+4+6(-9)+(+15)-(-9)​

= 12+12+4+6(-9)+15-(-9)

= 24+4+6(-9)+15-(-9)

= 28+6(-9)+15-(-9

= 28+(-54)+15-(-9)

= 28-54+15-(-9)

= -26+15-(-9)

= -26+(15+9)

= -26+24

= -2
