Question

Реши уравнение : 2 3/5:(x+1 3/14)- 1 2/5=1/3
помогите пожалуйста решить
буду очень благодарна !!!!!!!!!!!!!!!!!!!!

Answer 1

2 3/5:(x+1 3/14)- 1 2/5=1/3
13/5 : (х + 17/14) = 1/3 + 7/5
13/5 : (х + 17/14) = 5/15 + 21/15
13/5 : (х + 17/14) = 26/15
х + 17/14 = 13/5 : 26/15
х + 17/14 = 13/5 * 15/26
х + 17/14 = 3/2
х = 3/2 - 17/14
х = 21/14 - 17/14
х = 4/14 = 2/7
Проверка:
2 3/5 : (2/7 + 1 3/14) - 1 2/5 = 1/3
13/5 : (2/7 + 17/14) - 7/5 = 1/3
13/5 : (4/14 + 17/14) - 7/5 = 1/3
13/5 : 21/14 - 7/5 = 1/3
13/5 * 14/21 - 7/5 = 1/3
182/105 - 7/5 = 1/3
182/105 - 147/105 = 1/3
35/105 = 1/3
7/21 = 1/3
1/3 = 1/3

Answer 2

2 3/5:(x+1 3/14)- 1 2/5=1/3

13/5:(x+17/14) - 7/5 = 1/3
13/5:x + 13/5:17/14 - 7/5 = 1/3

13/5:17/14= 13/5*14/17 = 182/85
182/85 - 7/5 = 182/85 - 119/85= 63/85

1/3 -63/85 =  85/255 -189 /255 = -104/255

13/5:x= -104/255    x = -104/255:13/5= -104/255*5/13=-8/51

Ответ:  Х = -8/51
