Question

Решить уравнение (x+2 9/11)-4 10/11=1 4/11

Answer 1

(х+2 9/11)=1 4/11+4 10/11
х +2 9/11= 5 14/11
х= 5 14/11- 2 9/11
х= 3 5/11

Проверка :
( 3 5/11+2 9/11)- 4 10/11=1 4/11
5 14/11 - 4 10/11= 1 4/11
1 4/11= 1 4/11

(х-1 8/9)= 4 4/9-3 7/9
х-1 8/9= 40/9-34/9
х-1 8/9= 6/9
х= 6/9+1 8/9
х= 1 14/9=2 5/9

Проверка:
(2 5/9-1 8/9)+3 7/9= 4 4/9
(1 14/9-1 8/9)+3 7/9= 4 4/9
6/9+3 7/9= 4 4/9
3 13/9= 4 4/9
4 4/9=4 4/9
Думаю так

Answer 2

( x+$2\frac{9}{11}$ )-$4\frac{10}{11}$ = $1\frac{4}{11}$
-$4\frac{10}{11}$х + $\frac{1674}{121}$ = $\frac{15}{11}$
-$4\frac{10}{11}$х = $\frac{165}{121}$ - $\frac{1674}{121}$ 
-$4\frac{10}{11}$х = -$\frac{1509}{121}$
-$\frac{54}{11}$х = -$\frac{1509}{121}$
х = $\frac{1509}{594}$
