Answer 1

Resposta:

58

Explicação passo-a-passo:

{ [ (8×4+3)÷7+(3+15÷5)×3]×2}+12=

$\left(8\times \:4+3\right)\div \:7+\left(3+15\div \:5\right)\times \:3=$

$=35\div \:7+\left(3+15\div \:5\right)\times \:3$

$=35\div \:7+6\times \:3$

$=5+6\times \:3$

$=5+18$$=23$

$=23\times \:2+12$

$=46+12$

$=58$
