Porfaaa!

Answer 1

Explicación paso a paso:

a)

-13+{-5-[-2-(-3-1)+(-7)]-(-6+1-3)}-5=-10

-13+{-5-[-2-(-4)+(-7)]-(-8)}-5=-10

-13+{-5-[-2+4-7]+8}-5=-10

-13+{-5-[-5]+8}-5=-10

-13+{-5+5+8}-5=-10

-13+{8}-5=-10

-13+8-5=-10

-10=-10

b)

-3+8-(-3)+4-[3-(-4+7-5+1)-2+(-3)]-9=4

-3+8+3+4-[3-(-1)-2-3]-9=4

-3+8+3+4-[3+1-2-3]-9=4

-3+8+3+4-[-1]-9=4

-3+8+3+4+1-9=4

4=4

c)

4-{6+[3-(10-6)+7]-(5-2)}+9=4

4-{6+[3-(4)+7]-(3)}+9=4

4-{6+[3-4+7]-3}+9=4

4-{6+[6]-3}+9=4

4-{6+6-3}+9=4

4-{9}+9=4

4-9+9=4

4 = 4

d)

-(7-2)+{-[9-(14-5)+3]}+8=0

-(5)+{-[9-(9)+3]}+8=0

-5+{-[9-9+3]}+8=0

-5+{-[3]}+8=0

-5+{-3}+8=0

-5+-3+8=0

0=0
