Question

математика срочно.....​

Answer 1

Ответ:

$\frac{5}{6}x+\frac{2}{3} =x\\\\\frac{5}{6}x-x = -\frac{2}{3} \\\\\frac{5}{6}x-\frac{x}{1} =-\frac{2}{3} \\\\\frac{5x}{6}-\frac{6x}{6} =-\frac{2}{3}\\\\-\frac{x}{6} =-\frac{2}{3}\\\\\frac{x}{6} =\frac{4}{6}\\\\x =4$

Проверка:

$\frac{5}{6}*4+\frac{2}{3}=4\\\\\frac{20}{6} +\frac{2}{3}=4\\\\\frac{20}{6} +\frac{4}{6}=4 \\\\\frac{24}{6} =4\\\\4=4$
