Answer 1

Resposta:

100

Explicação passo a passo:

{[(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

= 100

Answer 2

$\boxed{{100}}$

Explicação:

(((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

100
