Решите уравнение 1)6 5/27-(х-1 2/9)=3 20/81 2)3 5/36-(1 4/9-х)=1 17/18

$6 \frac{5}{27} - ( x - 1 \frac{2}{9} )= 3 \frac{20}{81}x - 1 \frac{2}{9} = 6 \frac{5}{27} - 3 \frac{2}{81}x- 1 \frac{2}{9} = 6 \frac{15}{81} - 3 \frac{2}{81 x - 1 \frac{2}{9} = 3$ $\frac{13}{81}x = 3 \frac{13}{81} + 1 \frac{2}{9}x = 3 \frac{13}{81} + 1 \frac{18}{81}x= 4 \frac{34}{81}$
------------------
Ответ: $4 \frac{34}{81}$ .
$3 \frac{5}{36} - (1 \frac{4}{9} - x) = 1 \frac{17}{18} 1 \frac{4}{9} -x = 3 \frac{5}{56} - 1 \frac{34}{56} 1 \frac{4}{9} -x = 2 \frac{1}{56} x= 1 \frac{4}{9} - 2 \frac{1}{56} x=$ ...
