​

Answer 1

Respuesta:

Explicación paso a paso:

-16+8+( )=0

-8 + x = 0

x = 8

-16+8+(+8)=0

8-(-5+4)+( )=0

8 - (-1) + x = 0

8 + 1 + x = 0

9 + x = 0

x = -9

8-(-5+4)+(-9)=0

-10+5+(-12)-( )=0

-5 - 12 - x = 0

-17 - x = 0

-x = 17

x = -17

-10+5+(-12)-(-17)=0

-( )-(-5+8)=0

-x - (-5 + 8) = 0

-x - 3 = 0

-x = 3

x = -3

-(-3)-(-5+8)=0
