Question

5(x+10)*10(54/5-6)
$\sqrt{?}$
​

Answer 1

$5(x + 10) \times 10( \frac{54}{5} - 6) \\ \\ 5x + 50[10( \frac{54 - 30}{5} )] \\ \\ 5x + 50[10( \frac{24}{5} )] \\ \\ 5x + 50[10(4.8)] \\ \\ 5x + 50(48) \\ \\ 240x + 2400 \\ \\ 240(x + 10) \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ 240(x + 10 ) = 0 \\ x + 10 = \frac{0}{240} \\ x + 10 = 0 \\ x = 0 - 10 \\ x = - 10$
