Question

¿saben cual es la respuesta?

Answer 1

Respuesta:

(a +b )= (-1 + 3) = 2

(a+b) = (+4 + -2) = (+4 - 2)= 2

(a+b) = (-6 + 1) = -5

Explicación paso a paso:

(b-c) = (3 - -2) = (3 + 2) = 5

(b-c) = (-2-5) = -7

(b-c) = ( +1 -4)= -3

(a+c) = (-1+-2)= (-1-2) = -3

(a+c)= (+4+5)=9

(a+c)= (-6+4) = -2
