g) {[(8×4+3)÷7+(3+15÷5)×2-(9-7)+6}×2+12=


ME AJUDEM!!!!

Answer 1

E) 60÷{2×[-7+18÷(-3+12)]}-[7×(-3)-18(3+12)]}-7 (-3)-18÷(-2)+1]=

60÷{2×[-7+18÷(+9)]}-[7×(-3)-18(+15)]}-7 (-3)-(-9)+1]=
60÷{2×[-7+2]}-[7×(-3)-270]}+21+9+1]=
60÷{2×[-5]}-[-21-270]}+31]=
60÷{-10}-[-291]}+31]=
60÷{-10}-[-291+31]=
60÷{-10}-[-260]=
-6-[-260]=
-6+260=
+ 254

g) {[(8×4+3)÷7+(3+15÷5)×2-(9-7)+6}×2+12=
    {[(32+3)÷7+(3+3)×2-(+2)+6}×2+12=
    {[(35)÷7+(6)×2-(+2)+6}×2+12=
    {[(5+12-2+6}×2+12=
    {1}×2+12=
    2x12
