Question

0,5-8/9x=-3x-2 2/3 математика срочно​

Answer 1

Ответ:

-4.5

Пошаговое объяснение:

$0.5-\frac{8}{9}x=-3x-2\frac{2}{3}\\\\-\frac{8}{9}x+3x=-\frac{8}{3}-\frac{5}{10} \\\\ -\frac{8}{9}x+\frac{27}{9}x=-\frac{80}{30} -\frac{15}{30}\\\\\frac{19}{27}x=-\frac{95}{30}\\\\ x=-\frac{95}{30}:\frac{19}{27}\\\\ x=-\frac{95}{30}*\frac{27}{19}\\\\ x=-\frac{45}{10}\\\\ x=-4.5$
