a) -4 - { -3 [-4 + 10 – (4 – 9) + (10 -8)+3] -3} -6 =
• -4 - { -3 [+6 – (-5) + (2)+3] -3} -6
• -4 + 3 [+6 + 5) + (2)+3] -3} -6
• -1 +[16] -9
• 6
b) 2(1+7) – {[(2-3)-(2+8)]+(10-1)} =

• 16 – {-2}
• 16 + 4
• 20
(No estoy segura, pero creo que es valor absoluto)
a) | -10| = 10
b) |12| = 12
c) | -8| = 8
d) | 5| = 5
a) 3 (3x +1 ) –( x-1) = 6(x+10)
• 9x + 3 -x + 1 = 6x + 60
• 2x =56
• x = 28
b) 4x -5 =3x -3 -4
• x = -7 + 5
• x = -2
