3x=8................

Answer 2

Ответ:

$x=\frac{8}{3}=2\frac{2}{3}$

Пошаговое объяснение:

$5\frac{3}{14}x-4\frac{8}{21}x=2\frac{2}{9}\\\frac{73}{14}x-\frac{92}{21}x=\frac{20}{9}\\\frac{3* 73x}{3*14}-\frac{2*92x}{2*21}=\frac{20}{9}\\\frac{219x-184x}{42}=\frac{20}{9}\\\frac{35x}{42}=\frac{20}{9}\\\frac{5}{6}x=\frac{20}{9} |*\frac{6}{5} \\\\\frac{5x}{6} *\frac{6}{5}=\frac{20}{9}*\frac{6}{5}\\\\x=\frac{6}{5}*\frac{20}{9}\\ x=\frac{8}{3}=2\frac{2}{3}$
