Question

+5(-3+7)+4(8÷2)-(5+6-9) =​

Answer 1

+5(-3+7)+4(8÷2)-(5+6-9)​

$5\left(-3+7\right)+4\left(8\div \:2\right)-\left(5+6-9\right)$

Calculamos paréntesis:

$=5\cdot \:4+4\left(8\div \:2\right)-\left(5+6-9\right)$

$=5\cdot \:4+4\cdot \:4-\left(5+6-9\right)$

$=5\cdot \:4+4\cdot \:4-2$

Multiplicamos y dividimos:

$=20+4\cdot \:4-2$

$=20+16-2$

Sumamos y restamos:

$=34$

$\boxed{Resultado}$

34
