Answer 1

Olá!

{[(8×4+3)÷7+(3+15÷5)×3]×2-(19-7)÷6}×2+20

=> {[(32+3)÷7+(3+3)×3]×2-12÷6}×2+20

=> [(35÷7+6×3)×2-2]×2+20

=> [(5+18)×2-2]×2+20

=> (23×2-2)×2+20

=> (46-2)×2+20

=> 44×2+20

=> 88+20

=> 108

Espero ter ajudado!

Answer 2

{[(35)/7+(6)x3]x2-(12)/6}x2+20
{[5+18]x2-2}x2+20
{[23]x2-2}x2+20
{46-2}x2+20
{44}x2+20
88+20 = 108
