2 1/2+4 1/2(3 2/5-1 1/2у)=4 1/6 Помогите, пожалуйста!!!

это поделить либо вычесть?

2 1/2+4 1/2(3 2/5-1 1/2у)=4 1/6

(22+1)/2+ (24+1)/2 :

(35+2)/5- (12+1)/2 : у= (46+1)/6


5/2+ 9/2 : 17/5- 3/2: у = 25/6


9/2: 17/5- 3/2: у = 25/6- (53)/(23)

9/2: 17/5- 3/2: у = 25/6- 15/6

9/2: 17/5- 3/2: у = 10/6

9/2: 10/6= 17/5- 3/2: у

9/2 6/10 = 17/5- 3/2: у

уменьшаем 2 и 6 на 2.

9/1 3/10= 17/5- 3/2: у

27/10- 17/5= (-3/2: у)

27/10- (172)/(52)= (-3/2: у)

27/10- 34/10= (-3/2: у)

-7/10 = (-3/2: у)

-7/10 у= (-3/2)

У= (-3/2): (-7/10)

У= (-3/2) (-10/7)

Сокращается 2 и 10 на 2; (-) и (-) будет (+)

у= 3/1 5/7

У= 15/7

У= 2 1/7 ответ.


Проверка

2 1/2+4 1/2(3 2/5-1 1/2у)=4 1/6

2 1/2+ 4 1/2: (3 2/5- 1 1/2: 2 1/7)= 4 1/6

2 1/2+ 4 1/2: (3 2/5- (12+1)/2: (27+1)/7) = 4 1/6

2 1/2+ 4 1/2: ( 3 2/5- 3/2: 15/7)= 4 1/6

2 1/2+ 4 1/2: (3 2/5- 3/2 7/15)= 4 1/6
Уменьшаем 3 и 15 на 3.

2 1/2+ 4 1/2: ( (35+2)/5- 1/2 7/5)= 4 1/6

2 1/2+ (42+1)/2 : (17/5- 7/10)= 4 1/6

2 1/2+ 9/2: ( (172)/(52)- 7/10)= 4 1/6

2 1/2+ 9/2: (34/10- 7/10)= 4 1/6

2 1/2+ 9/2: 27/10= 4 1/6

2 1/2+ 9/2 10/27= 4 1/6
Уменьшаем 9 и 27 на 9, 2 и 10 на 2.

2 1/2+ 1/1 5/3= 4 1/6

2 1/2+ 5/3= 4 1/6

2 1/2+ 1 2/3= 4 1/6

2 (13)/(23)+ 1 (22)/(32)= 4 1/6

2 3/6+ 1 4/6= 4 1/6

3 7/6= 4 1/6

4 1/6= 4 1/6
