Answer 1

Olá.

{[(8·4+3)÷7+(3+15÷5)·3]·2–(19–7)÷6}·2+12=
{[(32+3)÷7+(3+3)·3]·2–(19–7)÷6}·2+12=
{[(35)÷7+(6)·3]·2–(12)÷6}·2+12=
{[35÷7+6·3]·2–12÷6}·2+12=
{[5+18]·2–2}·2+12=
{[23]·2–2}·2+12=
{23·2–2}·2+12=
{46–2}·2+12=
{44}·2+12=
44·2+12=
88+12=

Answer 2

{[(8 · 4 + 3) ÷ 7 + (3 + 15 ÷ 5) · 3] · 2 – (19 – 7) ÷ 6} · 2 + 12 
{[(32 + 3) ÷ 7 + (3 + 3) · 3] · 2 – 12 ÷ 6} · 2 + 12 
{[35 ÷ 7 + 6 · 3] · 2 – 2} · 2 + 12 
{[5 + 18] · 2 – 2} · 2 + 12 
{23 · 2 – 2} · 2 + 12 
{46– 2} · 2 + 12 
44 · 2 + 12 
88 + 12
