⭐ Ecuaciones Combinadas⭐

c) 6-(-9+7-1)-(3-(-5+4 +6)- 1]=

=6−(−2−1)−(3−(−5+4+6)−1)

=6−(−3)−(3−(−5+4+6)−1)

=9−(3−(−5+4+6)−1)

=9−(3−(−1+6)−1)

=9−(3−5−1)

=9−(−2−1)

=9−(−3)

=12 → Respuesta

d) 28 - [21-(12 - 3)-7]

=28−(21−9−7)

=28−(12−7)

=28−5

=23 → Respuesta

e) (-2+3.(2-5): 3]-[(3 - 5 + 2) - 2.(3-4)]

=−2+(3)(−3)3−(3−5+2−2(3−4))

=−2+−9/3−(3−5+2−2(3−4))

=−2+−3−(3−5+2−2(3−4))

=−5−(3−5+2−2(3−4))

=−5−(−2+2−2(3−4))

=−5−(0−2(3−4))

=−5−(0−(2)(−1))

=−5−(0−(−2))

=−5−2

=−7 → Respuesta

18- [6-(-3 + 7)-6]+43

=18−(6−4−6)+43

=18−(2−6)+43

=18−(−4)+43

=22+43

=65 → Respuesta
