Question

9/11 x (x - 2 /3 ) равно 50 ​

Answer 1

$x - \frac{2}{3}=50: \frac{9}{11}\\  \\x - \frac{2}{3}=50\cdot  \frac{11}{9}$

$\\x - \frac{2}{3}=\frac{550}{11}\\  \\x=\frac{450}{11}+\frac{2}{3}\\  \\x=\frac{550\cdot 3+2\cdot 11}{33} \\\\   x=\frac{1672}{33} \\ \\x=51\frac{22}{33}\\ \\ x=51\frac{2}{3}$
